Bodies of Water spans the rivers, lakes, oceans, seas, bays, and straits that have shaped civilizations, drawn borders, and connected cultures across millennia. With over 3,400 clues, it ranks among the most frequently tested geography topics on Jeopardy!, appearing in nearly every season since the show's 1984 debut.
Rivers dominate the topic with nearly 1,000 clues and over 100 recurring answers. European and American rivers are tested most heavily, with the Nile, Amazon, Rhine, Thames, and Mississippi forming the core. Lakes account for 450+ clues, with emphasis on the Great Lakes, African rift lakes, and culturally significant European lakes. Oceans and seas are tested through their geography (what borders them, what flows into them) rather than raw facts. Bays, gulfs, and straits round out the topic with clues that often test political geography and historical chokepoints.
Study strategy: Higher-value clues tend to test rivers by their tributaries, the cities on their banks, or historical events along their route. Daily Doubles favor lesser-known European rivers and African lakes. Final Jeopardy gravitates toward Lake Victoria, the Great Salt Lake, and the Bay of Bengal. The most reliable shortcut in this topic: know which sea or ocean each major river empties into.
The Nile, the world's longest river at approximately 4,130 miles, flows northward through northeastern Africa from its sources south of the equator to its vast delta on the Mediterranean Sea. For more than five thousand years its annual floods deposited rich silt across Egypt's narrow valley, creating one of history's earliest and most enduring civilizations, prompting the ancient Greek historian Herodotus to observe that "Egypt is the gift of the Nile." In Homer's Odyssey, both the river and the land are called Aigyptos.
The river's two principal branches; the Blue Nile, rising in the Ethiopian highlands near Bahir Dar, and the White Nile, fed by Lake Victoria, converge at Khartoum, the capital of Sudan. South of Khartoum, the Atbara River joins as the Nile's last tributary. The drainage basin, spanning 35 degrees of latitude, is the longest of any river on Earth. Lake Victoria, Africa's largest lake, serves as the Nile's chief reservoir and principal source, though the most remote headstream is the Ruvironza (or Kagera) River in Burundi.
The Aswan High Dam, completed in the 1960s, ended the ancient cycle of annual flooding and created Lake Nasser, a massive reservoir that took thirteen years to fill (the Sudanese portion is called Lake Nubia). At the Mediterranean, the delta splits into two main distributaries; the Rosetta and Damietta branches. The Rosetta branch lent its name to the Rosetta Stone, discovered nearby in 1799. Ancient Egyptians believed the river rose and flooded when the goddess Isis wept, and Ptolemy guessed the location of its source almost two thousand years before it was confirmed.
The Amazon is the greatest river of South America and the largest drainage system in the world by volume, carrying roughly one-fifth of all fresh water that flows into the world's oceans, more than the Mississippi, Yangtze, and Nile combined. It stretches approximately 4,000 miles from glacier-fed lakes in the Peruvian Andes to its mouth on the Atlantic coast of Brazil, where the river widens to nearly 150 miles and the island of Marajó, sitting in the delta, is roughly the size of Switzerland. The river's basin spans 2.7 million square miles across seven South American countries.
Francisco de Orellana, the first European to navigate its full length in 1542, named the river after female warriors who attacked his expedition, evoking the Amazons of Greek mythology. Its upper branches (the Marañón and Ucayali) flow through Peru; the Rio Negro, its largest tributary, is called the Guainía in Colombia. Other major tributaries include the Madeira and Purus, with over 200 tributaries in Brazil alone. The river is known as the Solimões before it reaches Manaus.
The Amazon's wildlife is legendary: piranhas, river dolphins, and the arapaima (also called pirarucu); one of the world's largest freshwater fish at nearly ten feet. Iquitos, Peru is the largest city in the world unreachable by road; oceangoing ships can travel 1,000 miles upstream to the Brazilian port of Manaus. In Spanish and Portuguese, the river's name is the same (Amazonas) two letters longer than in English.
The Rhine, one of Europe's great rivers and its most important commercial waterway since Roman times, rises from two small headstreams in the Swiss Alps and flows approximately 820 miles north through six countries, Switzerland, Liechtenstein, Austria, Germany, France, and the Netherlands, before emptying into the North Sea. It forms Liechtenstein's western border with Switzerland, passes through Lake Constance (bordered by Switzerland, Germany, and Austria), and is navigable from its mouth all the way to Basel, Switzerland's main port.
The Lorelei, a steep cliff on the river's right bank in Germany, is the subject of one of the most famous legends in German literature, Heinrich Heine's poem about a siren whose singing lured sailors to their deaths. Major cities along its banks include Vaduz, Basel, Strasbourg, Mainz, Cologne, Bonn, Düsseldorf, and Arnhem. Its chief tributaries (the Moselle, Main, and Neckar) are frequently tested. In the Netherlands, the river divides into three branches: the Waal, the Lek, and the IJssel, and its name is spelled Rijn. The Hudson River has been nicknamed "America's Rhine" for its natural beauty.
Watch out: The Rhine's high stumper rate (21%) stems from confusion with the Danube and Rhône. The key: the Rhine flows north to the North Sea; the Danube flows east to the Black Sea; the Rhône flows south through France to the Mediterranean.
The Thames, one of Britain's two longest rivers alongside the Severn, rises from headstreams in the Cotswold Hills (including the Churn and the Leach) and flows approximately 215 miles to an estuary on the North Sea. Its traditional source is marked by a stone in a field 356 feet above sea level, roughly three miles southwest of Cirencester. As it passes through Oxford, the river is also known as the Isis.
The Thames is London's defining geographic feature, dividing the city and giving rise to the famous distinction between the Left Bank and Right Bank. The Henley Royal Regatta, held on the Thames since 1839, is one of the world's premier rowing events. Cleopatra's Needle and Paul's Walk stand on its north bank; the Millennium Pedestrian Bridge, opened in 2000, was designed to perfectly frame St. Paul's Cathedral. The section near London Bridge is called the Pool.
The world's first major underwater tunnel, connecting Rotherhithe and Wapping, was completed beneath the Thames in 1843 by Marc Brunel. When the river flooded in 1928, it inundated the storerooms of the Tate Gallery. In 1858, sewage in the Thames caused Parliament to shut down due to the stench, a period Britons remember as "the Great Stink." Several structures called London Bridge have spanned the river, with the latest completed in 1972.
The Mississippi, the longest river in North America, drains approximately 1.2 million square miles (about one-eighth of the continent) as it flows 2,340 miles from Lake Itasca in Minnesota to its delta southeast of New Orleans on the Gulf of Mexico. Its name derives from Ojibwe words meaning "Father of Waters." The river forms or borders ten states, and its drainage basin covers all or part of thirty-one.
The Ohio River joins the Mississippi at Cairo, Illinois, actually contributing more water at that point than the Mississippi itself. The Missouri River, its longest tributary, enters near St. Louis. Other tributaries include the Arkansas (whose mouth is navigable to Tulsa), the Big Black, and the Red. The river's widest point, three and a half miles, lies just north of Clinton, Iowa. The Falls of Saint Anthony prevent navigation north of St. Paul.
Mark Twain's association with the river runs deep; his pen name comes from the riverboat term "mark twain" (two fathoms deep), and his 1883 book described the river as "rolling its mile-wide tide along, shining in the sun." In an 1884 novel, Huck and Jim raft down its length. The Robert E. Lee beat the Natchez in a famous 1870 steamboat race. In 1832, Henry Schoolcraft identified Lake Itasca as the river's source; the name Itasca derives from Latin words for "truth" and "head."
The Missouri River, the longest tributary of the Mississippi system, runs approximately 2,341 miles from Three Forks, Montana, where the Jefferson, Madison, and Gallatin rivers converge, all named for the president and secretaries who commissioned the Lewis and Clark expedition, to its mouth seventeen miles north of St. Louis. It is actually longer than the Mississippi from source to confluence.
"Sent up the Missouri" was slang for being sent to the federal penitentiary at Leavenworth, Kansas, which the river passes on its journey through Kansas City. Lake of the Ozarks, one of the largest man-made lakes in the United States, was created by damming a Missouri tributary.
Watch out: The Missouri is frequently confused with the Mississippi. The key: the Missouri is the Mississippi's longest tributary, flowing from Montana to St. Louis. If the clue mentions Three Forks, Lewis and Clark, or Kansas City, the answer is the Missouri.
The Danube, the second longest river in Europe after the Volga, originates in Germany's Black Forest, where two small springs, the Breg and the Brigach, unite at Donaueschingen, and flows approximately 1,770 miles eastward to the Black Sea, passing through or bordering ten countries, more than any other river in the world. In Germany, where it rises in the forest, the river is called the Donau.
Johann Strauss II immortalized it in his waltz "The Beautiful Blue Danube," though the river is actually brown or green for most of its length. Four national capitals sit on its banks (more than any other river) including Vienna, Bratislava, Belgrade, and Budapest, where it divides the city into hilly Buda on the west bank and flat Pest on the east. The Széchenyi Chain Bridge was the first to permanently span the river at Budapest. East of Belgrade, the Danube flows through a narrow gorge called the Iron Gate. Major tributaries include the Inn, Morava, Tisza (Hungary's longest river), and the Sava, which joins at Belgrade after flowing through Slovenia, Croatia, and Serbia. A canal linking the river directly to the Black Sea through Romania was completed in 1984.
The Seine rises on the Langres Plateau near Dijon, where in the nineteenth century the city of Paris purchased the land at its source and erected a statue of the goddess Sequana; and flows approximately 480 miles northwest across France before emptying into the English Channel at Le Havre, making it the second-longest river in France. The Marne joins it at Charenton-le-Pont, a suburb of Paris, and the Aube, Yonne, and Oise further divide its basin.
The river defines Paris. It turns so sharply on its trip through the capital that its west bank becomes its east, which is why Parisians say "Right Bank" (Rive Droite, associated with commerce) and "Left Bank" (Rive Gauche, associated with artists and intellectuals) rather than using compass directions. The Cathedral of Notre-Dame stands on the Île de la Cité, the city's oldest settlement, a small island in the river. The Pont Neuf, despite its name meaning "New Bridge," is Paris's oldest. In the opening ceremony of the 2024 Olympics, athletes arrived in a parade of boats sailing on the Seine. It is said that the ashes of Joan of Arc were thrown into its waters.
The Volga, the longest river in Europe at approximately 2,290 miles, rises in the Valdai Hills northwest of Moscow (where a pavilion marks its source) and flows south through the Russian heartland before emptying into the Caspian Sea, at a point roughly 92 feet below sea level. About 75% of the Caspian Sea's water comes from the Volga. The 80-mile Moscow Canal connects the Volga to the Russian capital, and the river and its tributaries carry about two-thirds of all Russian river freight.
Known as "Mother Volga" (Volga-Matushka), the river is inseparable from Russian national identity. In 1961, the city of Stalingrad was renamed Volgograd in its honor. During the sixteenth century, Ivan IV claimed the entire Volga valley for Russia. Major ports include Yaroslavl, Nizhny Novgorod (site of the Gorky Dam), Kazan (where it meets the Kazanka), and Rybinsk. Its greatest tributary, the Kama, stretches 1,100 miles. The Volga's famous boatmen are celebrated in the song "Yo, heave ho."
Watch out: The Volga is often confused with the Danube. The key: the Volga flows entirely within Russia to the Caspian Sea; the Danube flows through central Europe to the Black Sea.
The Ganges, the great river of the northern Indian subcontinent, is the holiest river in Hinduism, sacred from time immemorial. It begins in a Himalayan ice cave more than 10,000 feet above sea level and flows 1,560 miles through one of the most fertile and densely populated regions on Earth before emptying into the Bay of Bengal. Its delta, covering 30,000 square miles and shared with Bangladesh, is the world's largest. According to Hindu mythology, the river sprang from the foot of the god Vishnu; another legend says it was named for a Hindu goddess.
Varanasi (formerly Benares), one of the world's oldest continuously inhabited cities, sits on its banks. Ritual bathing in the Ganges is believed to wash away sins, and dying on its banks is said to guarantee eternal peace. It is an ancient custom to cremate the dead along the river at Varanasi. The city of Allahabad is considered holy for its location at the junction of the Ganges and the Jumna (Yamuna). Haridwar is a sacred site where the river emerges from the mountains onto the plains. In Kolkata, the Hugli (an arm of the Ganges) still draws bathers despite high pollution levels. The Brahmaputra joins the Ganges in Bangladesh.
The Colorado River flows approximately 1,450 miles from the Rocky Mountains through the American Southwest to the Gulf of California, carving some of the continent's most dramatic landscapes along the way, most famously the Grand Canyon. Lake Powell was created by the Glen Canyon Dam, and Lake Mead by the Hoover Dam, located about fifteen miles east of Las Vegas. Both are among the largest artificial lakes in the United States.
Watch out: There are multiple rivers named Colorado (one in Texas, one in Argentina), but Jeopardy almost always means the one that carved the Grand Canyon. Also note: the Royal Gorge in Colorado, over 1,000 feet deep, was carved by the Arkansas River: a common misdirect.
The Rio Grande (23 clues · 87% correct): One of the longest rivers in North America, the Rio Grande rises in the Rocky Mountains of Colorado and flows through the entire length of New Mexico before forming over half the border between the United States and Mexico, from El Paso to its mouth at Brownsville on the Gulf of Mexico. Known in Mexico as the Río Bravo del Norte, its name is simply Spanish for "large river." The Pecos and Conchos rivers are major tributaries. In the 1960s, the U.S. and Mexico built an artificial riverbed to prevent the river from shifting course and altering the international boundary.
The Columbia (23 clues): The Columbia River is the largest river in the Pacific Northwest, flowing from British Columbia through Washington and Oregon. It forms much of the Washington-Oregon border and is heavily dammed for hydroelectric power.
The Potomac (17 clues · 95% correct): The Potomac forms Virginia's northeast border and flows through Washington, D.C., where it is joined by the Anacostia; the two rivers flowing through the capital. George Washington's Mount Vernon sits on its banks, as does Harpers Ferry, where Robert Harper established a ferry crossing in the 1740s. John Quincy Adams used to skinny-dip in it. The river widens to eleven miles as it reaches Chesapeake Bay. Its name comes from an Iroquois word meaning "where goods are brought in."
The Jordan (19 clues · 94% correct): The Jordan River flows from Mount Hermon southward into the Dead Sea, passing through the Sea of Galilee along the way. In Arabic it is called Nahr Al-Urdunn. As the site where Jesus was baptized, the river holds immense religious significance across Christianity.
The Ohio (18 clues · 94% correct): Formed by the confluence of the Allegheny and Monongahela rivers at Pittsburgh, the Ohio flows southwest to join the Mississippi at Cairo, Illinois, actually contributing more water at that point than the Mississippi itself. It forms the northwest border of West Virginia.
The Mekong (18 clues · 89% correct): Southeast Asia's most important river, the Mekong flows through six countries (China, Myanmar, Laos, Thailand, Cambodia, and Vietnam) in a course of approximately 2,700 miles from the Tibetan Plateau to the South China Sea. Heavily tested in Double Jeopardy (15 of 18 clues).
The Tigris (6+ clues · 94% correct): The Tigris, whose name comes from a word meaning "arrow" (implying it flows faster than the Euphrates), rises from Lake Hazar in Turkey and flows about 1,150 miles south through Baghdad to Al Qurna, Iraq, where it merges with the Euphrates to form the Shatt al-Arab before reaching the Persian Gulf. Mosul, one of Iraq's largest cities, lies on its west bank.
The Euphrates (12 clues): The longest river in Southwest Asia, the Euphrates rises in Turkey and flows through Syria, where the Tabqa Dam created the country's largest reservoir, Lake Assad, before entering Iraq. The ancient city of Ur lay along its banks in the heart of the Fertile Crescent. At Al Qurna in southern Iraq, it joins the Tigris to form the Shatt al-Arab waterway. Fallujah and Raqqa are among the cities on its banks.
The Tiber (11 clues): Rome's river, called the Tevere in Italian, flows 252 miles through central Italy, though only the final twenty miles near Rome are navigable. Vatican City lies on its west (right) bank. Castel Sant'Angelo, originally built as Hadrian's mausoleum, sits on its shore. According to legend, a king of Alba Longa drowned in the river, which was then named for him. The oldest bridge in Rome, dating before the birth of Christ, spans its waters.
Lake Geneva, one of the largest lakes in western Europe, straddles the border of Switzerland and France. The French call it Lac Léman, and its shores host some of Europe's most storied cities: Geneva (where U.N. office workers overlook the lake with a view of the Alps), Lausanne, and Montreux, home of the annual Montreux Jazz Festival each July.
The Castle of Chillon, standing on a rocky islet at the lake's eastern shore, was immortalized by Lord Byron's 1816 poem "The Prisoner of Chillon" one of the most enduring literary-geography connections in quiz competition. Do not confuse with Geneva, New York, in the Finger Lakes region.
Lake Victoria, the largest lake in Africa and the second-largest freshwater lake in the world by surface area (after Lake Superior), lies mainly in Tanzania and Uganda but also borders Kenya. The explorer John Hanning Speke named it for Queen Victoria in 1858, when he became the first European to reach its shores and correctly identified it as a principal source of the Nile River, a connection that remains one of the highest-yield facts in geography.
The Ugandan city of Jinja sits at the lake's outlet, where the Nile begins its long journey north. In 1875, Henry Morton Stanley circumnavigated its shores. The lake was originally called Ukerewe by local peoples. Owen Falls Dam, built in the 1950s near Jinja, raised the lake's level by three feet. Its large gulfs include Speke Gulf in the southeast and Emin Pasha Gulf in the southwest. Entebbe and Kampala are key Ugandan ports on its shores. It has appeared in Final Jeopardy three times.
Lake Michigan, the third-largest of the Great Lakes by surface area, holds a unique distinction: it is the only Great Lake located entirely within the United States. All four others are shared with Canada. The Chicago River originally flowed into Lake Michigan; in 1900, engineers reversed its flow (one of the great engineering feats of the era) so that Chicago's sewage would travel toward the Mississippi via the Chicago Sanitary and Ship Canal rather than contaminating the city's drinking water.
The Great Salt Lake, situated in northern Utah, is the largest saltwater lake in the Western Hemisphere. Several streams flow into it, but none flow out, water leaves only by evaporation, concentrating the salts to levels that make drowning nearly impossible. The lake is the remnant of prehistoric Lake Bonneville, a massive Ice Age body of water that once covered much of western Utah. The Bonneville Salt Flats, where land-speed records are set, are part of the ancient lakebed. It has appeared in Final Jeopardy five times, more than almost any other body of water.
Lake Baikal, located in the southern part of eastern Siberia, is the oldest existing freshwater lake on Earth (formed in a rift valley approximately 25 million years ago) and the deepest continental body of water, plunging to 5,315 feet. It contains roughly one-fifth of the world's unfrozen fresh surface water, more than all five North American Great Lakes combined. More than 300 rivers and streams flow into it, but only one (the Angara River) flows out.
The island of Olkhon sits in its center. Baikal is home to species found nowhere else, including the Golomyanka (a translucent fish) and the nerpa, the world's only freshwater seal. Cities on its shore include Babushkin, a stop on the Trans-Siberian Railway, and the ports of Nizhneangarsk and Listvyanka. In 1990, scientists discovered colonies of marine life living in hydrothermal vents at its bottom. Among the world's lakes, Tanganyika is second only to Baikal in depth.
Lake Titicaca, the world's highest navigable lake, sits at 12,507 feet in the Andes on the border of Bolivia and Peru. According to Inca tradition, the first Inca emerged from an island in the lake. The pre-Incan Uros people still live on floating islands constructed of totora reeds, a way of life maintained for centuries. The lake's name derives from a Quechua phrase meaning "rock of the puma."
Lake Maracaibo, in northwestern Venezuela, is technically a tidal bay connected to the Gulf of Venezuela, though it has traditionally been called a lake. When the Spanish explorer Alonso de Ojeda reached it in 1499, the stilted houses along its shores reminded him of Venice, inspiring the name "Venezuela," meaning "Little Venice." Italian engineer Riccardo Morandi designed its famous bridge. Puerto Miranda and Cabimas are ports on its shores.
Watch out: Maracaibo has the highest stumper rate (53%) among frequently tested lake answers. The "Little Venice" origin story and the Ojeda connection are the most common clue angles.
Lake Superior (16 clues · 100% correct): The largest of the Great Lakes and the largest freshwater lake by surface area in the world, Superior is also the deepest and highest above sea level of the five. It is both the westernmost and northernmost Great Lake, containing more than half the water in the entire Great Lakes system. Longfellow called it "Gitche Gumee" ("shining big sea water") in The Song of Hiawatha. Michigan's Keweenaw Peninsula extends far into its waters, and Duluth is a major port on its shore. Fur trappers called it the "Upper Lake" in French, Lac Supérieur.
Lake Ontario (17 clues · 94% correct): The smallest of the Great Lakes, Ontario shares its name with a Canadian province and is nearly as large as New Jersey. The St. Lawrence River flows from it to the Atlantic.
Lake Huron (15 clues · 67% correct): The second-largest Great Lake by surface area, Huron has the longest shoreline of the five. Named for the Huron (Wyandot) people.
Lake Erie (15 clues · 64% correct): The shallowest and southernmost of the Great Lakes. The Cuyahoga River, which famously caught fire in 1969 and helped spark the modern environmental movement, flows into it.
Lake Pontchartrain (14 clues · 93% correct): Named for Louis XIV's marine minister, this Louisiana lake is central to the geography of New Orleans. Lake Borgne connects it to the Gulf of Mexico.
Lake Nasser (13 clues · 61% correct): Created by the Aswan High Dam on the Nile, Lake Nasser took thirteen years to fill. The Sudanese portion is called Lake Nubia.
The Finger Lakes (13 clues · 100% correct): A group of eleven elongated lakes in New York State, named for their shape. Cayuga and Seneca are the largest. 0% stumper rate.
Lake Mead (12 clues · 82% correct): Created by Hoover Dam on the Colorado River, located fifteen miles east of Las Vegas. One of the largest artificial lakes in the United States.
Lake Tanganyika (10 clues): Located in East Africa's Great Rift Valley, Tanganyika is the second-deepest lake in the world after Baikal and the longest freshwater lake, stretching 420 miles. Bordered by Tanzania, DRC, Burundi, and Zambia.
The Black Sea, bordered by Turkey, Georgia, Russia, Ukraine, Romania, and Bulgaria, is connected to the Mediterranean via the narrow Bosporus strait and the Sea of Marmara. The Danube empties into it after flowing across Romania, as do the Dnieper and Dniester rivers. The ancient Greeks called it Pontus Euxinus ("Hospitable Sea"), an ironic name, since it was considered dangerous.
The Crimean Peninsula, bordered by the Black Sea to the south and the much smaller Sea of Azov to the northeast, is connected to the Azov by the Kerch Strait. Its deep waters are nearly devoid of oxygen below 510 feet, making it one of the world's largest anoxic bodies of water, in Russian, Chernoye More. Ports include Odessa and Sevastopol in Ukraine, Samsun in Turkey, and Golden Sands, a resort on Bulgaria's east coast.
Watch out: Often confused with the Caspian Sea. The key: the Black Sea is a true sea connected to the Mediterranean; the Caspian is landlocked.
The Indian Ocean, the third-largest ocean, was called Mare Indicum by ancient Romans. Its most common test angle is route geography, "what ocean do you cross going from East Africa to India?" Madagascar, the world's fourth-largest island, sits in it off Africa's southeast coast. The Zambezi River flows into it.
The Caspian Sea is, despite its name, the world's largest lake, a distinction tested repeatedly. This vast, landlocked, saltwater body is bordered by Russia, Azerbaijan, Iran, Turkmenistan, and Kazakhstan. The Volga, Europe's longest river, supplies about three-quarters of its water. Its surface lies roughly 92 feet below sea level.
The Caspian is rich in oil reserves (particularly around Baku, Azerbaijan) and sturgeon; the source of beluga caviar. The Ural River flows 1,500 miles to reach it. The Kara-Bogaz-Gol Gulf in Turkmenistan is one of its most notable arms. Over the centuries, the Caspian has been shrinking due to extensive damming of its feeder rivers. It is also known as the Khazar Sea and the Mazandaran Sea.
The Mediterranean Sea takes its name from Latin (mare mediterraneum, "sea in the middle of the land") reflecting its centrality to ancient Western civilization. The Romans called it Mare Nostrum, "Our Sea." The Strait of Gibraltar connects it to the Atlantic; the Adriatic and Ionian Seas are its arms. The Ionian Sea is its deepest part.
An undersea ridge running from Tunisia to Sicily divides it into two basins. Rivers emptying into it include the Ebro from Spain and the Nile from Egypt. The Cinque Terre, five fishing villages on the Italian Riviera, overlook the Ligurian Sea, an arm of the Mediterranean bounded on the south by Elba and Corsica. Syria has about 100 miles of coastline on it, and the Gaza Strip lies along its eastern shore.
The Red Sea, part of the Great Rift Valley system, extends approximately 1,400 miles from the Strait of Bab el-Mandeb (connecting to the Gulf of Aden and Indian Ocean) northward to the Sinai Peninsula, where it divides into the Gulf of Aqaba and the Gulf of Suez. It is the sea that parted in the Book of Exodus. The ancient Greeks and Romans called it the Erythraean Sea.
The Suez Canal connects the Red Sea to the Mediterranean through Egypt. Jordan's only seaport, Al-Aqabah (Aqaba), lies on it. Jiddah in Saudi Arabia and Port Sudan are principal ports. Blooms of the algae Trichodesmium erythraeum may give it its color and name. The Coral Sea, by contrast, was named for its coral formations.
The Dead Sea, a landlocked salt lake between Israel and Jordan, holds the distinction of being the lowest body of water on the surface of the Earth; its shore lies roughly 1,400 feet below sea level. With salinity of about 34% (nearly ten times saltier than the ocean), it is also the world's saltiest body of water, making it almost impossible to drown in its buoyant waters. The Hebrew name is Yam Ha-Melah ("Salt Sea") and in Arabic it is called the Sea of Lot.
The Jordan River flows into the Dead Sea from the north, but no river flows out; water exits only through evaporation, and the lake has been shrinking steadily. A land bridge called al-Lisan separates it into a southern basin and a northern basin. The Dead Sea Scrolls, ancient religious manuscripts discovered in caves near Qumran on its northwest shore beginning in 1947, took their name from it. The biblical city of Sodom is believed to have stood nearby.
The North Sea lies between Britain, Scandinavia, and continental Europe. The Rhine empties into it. Belgium's seacoast (about forty miles long) is on the North Sea. The Strait of Dover connects it to the English Channel. Inchcape Rock, a dangerous reef off Scotland's coast, sits in its waters. North Sea oil, discovered in the 1960s, transformed the economies of Britain and Norway.
The Arctic Ocean, the world's smallest and shallowest ocean, surrounds the North Pole. The Laptev Sea is one of its marginal seas. Its greatest depth, nearly 18,000 feet, lies near Spitsbergen Island, part of Norway's Svalbard archipelago.
Watch out: With a 24% stumper rate, contestants sometimes blank on the name or confuse it with the Antarctic. The key: the Arctic Ocean is in the north, surrounding the North Pole.
The Pacific Ocean (13 clues · 87% correct): Named by Ferdinand Magellan from the Latin pacificus ("peaceful"), the Pacific is home to the deepest point on Earth; the Mariana Trench at 36,201 feet. The Sulu Sea is among its marginal seas.
The Bering Sea (13 clues · 80% correct): Bristol Bay, Alaska's major salmon fishery, is an arm of the Bering Sea. The Aleutian Islands mark its southern border.
The Baltic Sea (14 clues · 69% correct): Bordered by nine countries, Finland, Sweden, Denmark, Germany, Poland, Lithuania, Latvia, Estonia, and Russia; the Baltic's most notable geographic detail is Kaliningrad, a Russian exclave wedged between Poland and Lithuania on its coast.
The Adriatic Sea (13 clues · 92% correct): Named for the ancient Roman port of Adria near Venice, the Adriatic is an arm of the Mediterranean extending from the Gulf of Venice to the Strait of Otranto.
The Coral Sea (12 clues · 67% correct): Off Australia's northeast coast, named for its reef formations including parts of the Great Barrier Reef. Site of the 1942 Battle of the Coral Sea; the first naval battle fought entirely by aircraft carriers.
The Bay of Bengal, the world's largest bay, is bordered by India, Bangladesh, Myanmar, and Sri Lanka. Bangladesh's entire 350-mile coastline lies on this bay, making the low-lying nation extraordinarily vulnerable to cyclones. Myanmar's Irrawaddy River drains into it, as does the Ganges. Seaports include Chittagong (Bangladesh), Chennai (India), and Trincomalee (Sri Lanka).
The Bay of Biscay, a notoriously stormy arm of the Atlantic, lies between northern Spain and western France. Its name derives from the Basque Country, Biscay from the Basques. The beaches at San Sebastián, Spain, and Biarritz, France, front on it. Its maximum depth reaches 15,525 feet. A perfect gimme at 0% stumper rate.
The Gulf of Mexico is technically an arm of the Atlantic Ocean. The Bay of Campeche forms its southernmost part in Mexico. Sigsbee Deep, its deepest point, lies about 200 miles southeast of Brownsville, Texas. Both the Mississippi River's delta and the Rio Grande empty into it. Major ports include Houston, New Orleans, Tampa, and Veracruz.
Hudson Bay, explored by Henry Hudson in 1610 (who initially believed it was the long-sought Northwest Passage), is one of the largest bodies of water in Canada. The Foxe Channel connects it to the Arctic Ocean. The Hudson's Bay Company, founded in 1670 and one of the oldest commercial corporations in the world, took its name from this bay. In the early 1770s, Samuel Hearne became the first European to reach the Arctic Ocean overland from Hudson Bay.
The Persian Gulf (11 clues · 91% correct): Bordered by Iran, Iraq, Kuwait, Saudi Arabia, Bahrain, Qatar, and the UAE, the Persian Gulf has been central to global geopolitics since the discovery of oil in the region. The Strait of Hormuz connects it to the Gulf of Oman. The 1991 Gulf War brought its name into everyday vocabulary.
Puget Sound (10 clues · 100% correct): An arm of the Pacific in Washington state, dividing into Hood Canal and Admiralty Inlet. The Navy shipyard at Bremerton sits on it, and Whidbey is its largest island.
The Bay of Fundy (7 clues · 100% correct): Separating Nova Scotia and New Brunswick in eastern Canada, the Bay of Fundy is famous for the highest tides in the world, sometimes exceeding fifty feet. The tides can reverse the flow of the St. John River.
Chesapeake Bay (7 clues · 86% correct): About 200 miles long, bordered by Maryland and Virginia. The Delmarva Peninsula separates it from the Atlantic. The U.S. Naval Academy at Annapolis sits on its shores.
The Gulf of Tonkin (6 clues · 100% correct): Located between Vietnam and China, the Gulf of Tonkin entered American consciousness through the 1964 Gulf of Tonkin incident, alleged attacks on U.S. destroyers, which led to the Gulf of Tonkin Resolution and the escalation of American involvement in Vietnam.

The English Channel separates England from France along a stretch of roughly 350 miles. The French call it La Manche, "the sleeve." The Strait of Dover, its narrowest point at just 21 miles, connects it to the North Sea. The Channel Tunnel ("Chunnel"), opened in 1994, runs beneath it. Swimming the Channel has been a test of endurance since Captain Matthew Webb first accomplished it in 1875. The Seine empties into it at Le Havre.
The Strait of Dover, known to the French as the Pas de Calais, is the narrowest part of the English Channel, just 21 miles separating England from France. Winston Churchill reportedly called it "the world's best tank trap."
Watch out: At 80% stumper rate, this is the hardest answer in the entire topic. Contestants confuse it with the English Channel itself. The key: the Strait of Dover is specifically the narrowest part of the Channel, connecting it to the North Sea.
The Strait of Gibraltar connects the Mediterranean Sea to the Atlantic Ocean, separating Europe (Spain) from Africa (Morocco) by just 8.7 miles at its narrowest. In classical mythology, the Pillars of Hercules marked its entrance. The Rock of Gibraltar, a British Overseas Territory, commands its northern shore. Tarifa, Spain, and Tangier, Morocco, face each other across the strait.
The Panama Canal, a 51-mile artificial waterway connecting the Atlantic and Pacific oceans through Panama, was originally a French project under Ferdinand de Lesseps (the builder of the Suez Canal) before the United States completed it in 1914 at a cost of roughly $380 million. Ships approach from the Atlantic side via Limon Bay and pass through Gatun Lake, an artificial lake created during construction. The Chagres River supplies water for the locks. The Bridge of the Americas, built in the early 1960s, spans the canal.
