50 free Continents and Oceans trivia questions with answers — geography quiz, new questions added Aug 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 Russian Mir submersible measured 4,261 m of ocean at the pole in 2007, 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 went straight from Thursday 29 December to Saturday 31 December 2011, a change meant to improve business with trading partners to its west; Tokelau jumped with it.
Q 04Which country stretches across five geographical time zones yet officially keeps just one, set to its capital?
China
China runs entirely on UTC+8 despite spanning five geographical time zones, so in far-western Xinjiang the sun can rise after 9 a.m. by the official clock.
Q 05Which island pair in the Bering Strait, 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 Big Diomede runs 21 hours ahead of Little Diomede across the line.
Q 06Ceuta and Melilla, two autonomous cities on Morocco's northern coast, belong to which European country?
Spain
Spain has held Ceuta and Melilla for centuries; Ceuta sits just 17 km from Cádiz province across the Strait of Gibraltar, which makes Spain a transcontinental state.
Q 07Which island nation joined the European Union in 2004 even though it lies geographically in West Asia, off the Levant?
Cyprus
Cyprus sits off the coast of the Levant mainland in West Asia, yet political geography files it as a European country, complete with the euro.
Q 08Which country is the only one in Asia whose land the equator crosses, running through Sumatra and Borneo?
Indonesia
Indonesia is one of just eleven countries whose land the equator touches; the line passes through Pontianak, the capital of West Kalimantan on Borneo.
Q 09Which German meteorologist first proposed continental drift in a 1912 lecture, decades before geologists accepted it?
Alfred Wegener
Alfred Wegener's idea was not accepted by mainstream geology until the 1960s, and he died in 1930 on a Greenland expedition long before his vindication.
Q 10In which year did the National Geographic Society officially recognise the Southern Ocean as Earth's fifth ocean?
2021
In 2021 National Geographic's cartographers added the Southern Ocean to their maps, two decades after the International Hydrographic Organization drew its limits.
Q 11Hawaii, a US state, is geographically grouped with which continent-sized region, as part of Polynesia?
Oceania
Oceania takes in Hawaii along with Australasia, Melanesia, Micronesia and Polynesia, so the United States is counted among its partial members.
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, after Ursa Major, the Great Bear, which wheels over the northern sky.
Q 13Which dark volcanic rock, erupted along mid-ocean ridges, makes up almost all of the ocean floor's crust?
Basalt
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 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 is only 316 m at its deepest, a sill that separates the Tyrrhenian and western Mediterranean from the eastern basin.
Q 22The land inside the Arctic Circle is divided among how many countries, from Norway round to Iceland?
Eight
Eight countries share the Arctic Circle's land: Norway, Sweden, Finland, Russia, the United States, Canada, Denmark through Greenland, and Iceland.
Q 23Which vanished Mesozoic sea, named by Eduard Suess in 1893 after a Greek goddess, was crushed between colliding plates?
Tethys Ocean
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 was first completed solely by ship when Roald Amundsen brought the sloop Gjøa from Greenland to Alaska in 1906; in 2007 it opened without icebreakers.
Q 15Which warm flow, ridden by the sea turtles in Finding Nemo, sweeps south along Queensland and New South Wales?
East Australian Current
The East Australian Current is portrayed in Finding Nemo as a superhighway for fish and turtles; at its peak near 33°S it carries nearly 35 billion litres of water a second.
Q 16Which range is still rising about 5 mm a year because the Indian plate keeps pushing into the Eurasian plate?
Himalayas
The Himalayas were uplifted after the Indian plate collided with Eurasia, and the squeeze has never stopped, which is why the range is still geologically active.
Q 17What name do geographers give the single landmass of Africa, Europe and Asia, home to roughly 86% of humanity?
Afro-Eurasia
Afro-Eurasia, also called the World Island or the Old World, is the largest and most populous contiguous landmass on Earth.
Q 18Which strait carries the Europe–Asia line south from the Sea of Marmara to the Aegean, past the Gallipoli peninsula?
Dardanelles
The Dardanelles narrows to just 1,200 m, which is why Turkish troops could trap the Allied landings on the Gallipoli peninsula's shores.
Q 19What is the name of the 3% of Turkey that lies in Europe, west of the Turkish Straits?
East Thrace
East Thrace covers just 23,764 km² yet holds the European half of Istanbul, Turkey'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 follows the deep channel between the Asian and Australian continental shelves and was named by Thomas Henry Huxley after Alfred Russel Wallace.
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 lived about 275 million years ago on the shores of the Irati–Whitehill sea, whose bed is now split between two continents by the South Atlantic.
Q 25The Mid-Atlantic Ridge pushes 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 has opened the Atlantic to 85 million square kilometres since Pangaea began to split apart.
Q 26Why is almost no ocean floor older than 200 million years, while continental rocks reach four billion?
Subduction recycles it into the mantle
Subduction recycles it into the mantle as older, denser oceanic lithosphere sinks beneath lighter plates, so crust past 200 million years survives only in corners like the eastern Mediterranean.
Q 27Which continent drifts north-east about 7 cm a year, so its official map coordinates were shifted 1.8 m in 2017?
Australia
Australia's coordinates officially moved 1.8 metres northeast under the GDA2020 datum, a correction that took full effect on 1 January 2020 after 26 years of unlogged plate motion.
Q 28Which island nation erased 31 December 1994 from its calendar so the date line would bend east around all its atolls?
Kiribati
Kiribati's move put its Line Islands, including Kiritimati, first to greet the year 2000, ahead of every other country on Earth.
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.
