99 free Continents and Oceans trivia questions with answers — geography quiz, new questions added Oct 2026.
Seven continents and five oceans sound like settled facts, but the edges between them are anything but. A continent's border can run down a strait a few hundred metres wide, a bay deep inside one country can be filed under a far-off ocean, and an entire landmass can creep far enough that its map coordinates have to be redrawn. This quiz lives on those edges: the straits and depressions that mark where one continent becomes another, the countries that straddle two, the currents that warm or chill particular coasts, and the ancient oceans and supercontinents that explain why the modern map looks the way it does. Expect questions on the date line, polar seas, the deepest point of the newest ocean and the fossils that proved the continents once touched. It suits anyone who enjoyed an atlas as a child and still does: pub-quiz teams, geography students and teachers looking for questions with a reason behind every answer. Every question carries a short explanation and a source, so a surprising answer can be checked on the spot.

Q 01On a Mercator map Greenland looks as big as Africa; in reality Africa is about how many times larger?
14
Africa is about 14 times as large as Greenland, yet Mercator's 1569 projection stretches the far north until the two look equal on the page.
Q 02What lies directly beneath the geographic North Pole, which unlike the South Pole sits on no continent?
Sea ice over deep water
Sea ice over deep water is all there is: the ocean under the pole is more than 4,000 m deep and the ice above it never stops drifting, which is why no permanent station can stand there.
Q 03Which Pacific nation skipped 30 December 2011 entirely, hopping west across the date line toward its trading partners?
Samoa
Samoa was undoing an old switch: 119 years earlier it had moved to the American side of the date line to help trade with the United States, long before its main partners lay to the west.
Q 04Which country stretches across five geographical time zones yet officially keeps just one, set to its capital?
China
China runs on Beijing time from the coast to its western border, so far-western Xinjiang keeps an unofficial clock of its own, two hours behind, and people there use both.
Q 05Which island pair between Siberia and Alaska, one Russian and one American, sits 3.8 km apart across the date line?
Diomede Islands
The Diomede Islands are nicknamed Tomorrow Island and Yesterday Island, because the date line between them puts Big Diomede almost a full day ahead of its neighbour.
Q 06Ceuta and Melilla, two autonomous cities on Morocco's northern coast, belong to which European country?
Spain
Spain got Ceuta from Portugal: it was the one city of the Portuguese empire to side with Madrid when Portugal broke away in 1640, and Lisbon ceded it in 1668.
Q 07Which island nation joined the European Union in 2004 even though it lies geographically in West Asia, off the Levant?
Cyprus
Cyprus joined as a divided island: the whole of it counts as EU territory, but EU law is suspended in the north, where the government in Nicosia has no control.
Q 08Which country is the only one in Asia whose land the equator crosses?
Indonesia
Indonesia is crossed on Sumatra and Borneo, where the city of Pontianak marks the line with a monument; at the equinoxes the noon sun stands overhead and shadows there vanish for a moment.
Q 09Which German meteorologist set out the theory of continental drift in a 1912 lecture, decades before geologists accepted it?
Alfred Wegener
Alfred Wegener was dismissed by leading geologists as an outsider, a mere weatherman; he died on a Greenland expedition in 1930, and his idea only won out in the 1960s.
Q 10Which society recognised the Southern Ocean as a fifth ocean in 2021?
National Geographic Society
The National Geographic Society made the change on World Oceans Day, reasoning that the swift current circling Antarctica keeps those waters distinct: an ocean defined by a current, not by land.
Q 11Hawaii is a US state, but which island region of the Pacific does it share with Tahiti and Easter Island?
Polynesia
Polynesia reaches Hawaii because its first settlers were Polynesian voyagers, who arrived centuries before any European; the islands form the northern corner of the Polynesian Triangle.
Q 12The Arctic takes its name from the Greek arktos, meaning which animal, after the constellation of the same name?
Bear
Bear is the meaning of arktos: the Greeks named the north for the Bear, the constellation that circles the pole, and the Antarctic is simply the region opposite it.
Q 13Which dark volcanic rock, erupted along mid-ocean ridges, makes up most of the ocean floor's crust?
Basalt
Q 21Which 145 km gap between Italy's largest island and Tunisia splits the Mediterranean into western and eastern basins?
Strait of Sicily
The Strait of Sicily hides a restless volcano: in 1831 it broke the surface as a new island, four powers disputed who owned it, and within six months the sea had washed it away.
Q 22Which Arctic country's mainland lies wholly south of the Arctic Circle, which crosses only one of its small offshore islands?
Iceland
Iceland touches the Arctic Circle only at Grímsey, an island 40 km off its north coast, yet that sliver makes it one of the eight countries with land inside the line.
Q 23Which vanished Mesozoic sea, named by Eduard Suess in 1893 after a Greek goddess, was crushed between colliding plates?
Basalt forms the crustal part of every oceanic plate as mantle wells up beneath the ridges, while the continents ride higher on lighter granitic rock.
Q 14Which Arctic sea lane through Canada's island maze links the Atlantic and Pacific, first transited by ship in 1906?
Northwest Passage
The Northwest Passage had wrecked lavish expeditions, Sir John Franklin's of 1845 among them, before Roald Amundsen got through in a small sloop with a crew of six, taking three years.
Q 15Which warm ocean current do the sea turtles ride like a highway in Finding Nemo?
East Australian Current
The East Australian Current really does sweep tropical fish from the Great Barrier Reef to Sydney Harbour each summer, though nowhere near as fast as the film's turtles ride it.
Q 16Which range is still rising because the Indian plate keeps pushing into the Eurasian plate?
Himalayas
The Himalayas carry the proof of their origin: the rock at the very top of Everest is limestone full of sea-floor fossils, lifted more than 8 km as India ploughed into Asia.
Q 17Africa is joined to Eurasia, making Earth's largest landmass, only by which narrow neck of land, cut by a canal in 1869?
Isthmus of Suez
The Isthmus of Suez makes Africa, Europe and Asia a single landmass, home to about 86% of humanity; the canal dug across it spares ships the long voyage around Africa.
Q 18Which strait carries the Europe–Asia line south from the Sea of Marmara to the Aegean, past the Gallipoli peninsula?
Dardanelles
The Dardanelles was the ancient Hellespont: Xerxes had it bridged with boats so his army could march into Greece, and in 1810 Lord Byron swam across it from Europe to Asia.
Q 19What is the name of the 3% of Turkey that lies in Europe, west of the Turkish Straits?
East Thrace
East Thrace is just 3% of Turkey's land but home to more than a tenth of its people, because it takes in the European side of Istanbul, the country's largest city.
Q 20Which faunal boundary, drawn in 1859 between Bali and Lombok, splits Asian wildlife from the Australian realm?
Wallace Line
The Wallace Line runs between Bali and Lombok through a strait only a few dozen kilometres wide, yet so deep that it stayed open water even when ice-age seas fell, so few land animals ever crossed.
Tethys Ocean
The Tethys Ocean takes its name from the sister and consort of Oceanus; it was squeezed shut between colliding plates, throwing up the Alpide belt of mountains.
Q 24Which small Permian reptile, fossilised in Brazil, Uruguay and southern Africa, became evidence for continental drift?
Mesosaurus
Mesosaurus looked rather like a small crocodile and kept to inland waters; a creature like that could never have crossed an ocean, so the same fossils on both shores meant the lands were once joined.
Q 25The Atlantic widens at the Mid-Atlantic Ridge, carrying the Americas away from Europe and Africa at roughly what rate each year?
2.5 cm
About 2.5 cm a year sounds trivial, but it adds up to 25 km every million years, enough over 100 to 200 million years to turn a narrow inlet into the Atlantic.
Q 26Which plate-tectonic process explains why almost no ocean floor is older than 200 million years, while continental rocks reach four billion?
Subduction
Subduction sinks old, dense sea floor back into the mantle at the ocean trenches, while lighter continental rock stays afloat and keeps its ancient record.
Q 27Which continent drifts north about 7 cm a year, so its official map coordinates were shifted 1.8 m in 2017?
Australia
Australia had crept about 1.5 m since its map grid was last fixed in 1994, enough to trip up satellite navigation, so the 1.8 m correction deliberately overshot to stay accurate until 2020.
Q 28Which island nation erased 31 December 1994 from its eastern atolls' calendar so that all its atolls would share one date?
Kiribati
Kiribati had been cut in two by the date line, its two sides sharing only four working days a week; the fix also made its Line Islands the first land to greet the year 2000.
Q 29The Amundsen–Scott station at the South Pole, where every time zone meets, keeps the clocks of which country?
New Zealand
New Zealand time rules there because the station's main supply base is Christchurch, and McMurdo on the coast keeps the same clocks.
Q 30Mean sea level at the Panama Canal's Pacific end sits roughly how much higher than at its Atlantic end?
20 cm
About 20 cm of extra height comes from the Pacific's less dense water and prevailing weather, though the canal's locks exist to climb the hills between, not to bridge that step.
