Free World Geography MCQs with Answers

• A. 10°
• B. 55°
• C. 15°
• D. 5°

Explanation: Subtracting 20° from 35° gives a 15° difference.

• A. 15°
• B. 5°
• C. 25°
• D. 35°

Explanation: From 20° N down to the Equator is 20°, plus 15° to 15° S, totalling 35°.

• A. About 11 kilometres
• B. About 111 kilometres
• C. About 1,111 kilometres
• D. About 1,011 kilometres

Explanation: One degree of latitude corresponds to roughly 111 km on the ground.

• A. 1,110 kilometres
• B. 555 kilometres
• C. 55 kilometres
• D. 111 kilometres

Explanation: Five degrees of latitude at 111 km each gives 555 km.

• A. No; it is smallest at the Equator and increases towards the poles
• B. Yes, it is 111 km everywhere
• C. Yes, except at the poles
• D. No; it is greatest at the Equator and decreases towards the poles

Explanation: Meridians converge toward the poles, so a degree of longitude shrinks with latitude.

• A. 340°
• B. 180°
• C. 10°
• D. 20°

Explanation: The two meridians are 10° on either side of the 180° line, so the smaller gap is 20°.

• A. Points where the Equator meets the prime meridian
• B. The two tropics
• C. Two points directly opposite each other on Earth, with opposite latitudes and longitudes differing by 180°
• D. Points on the same meridian at equal latitudes

Explanation: Antipodes are diametrically opposite points on the globe.

• A. An underground water reserve
• B. A coastal inlet of the ocean
• C. A flowing channel of water reaching the sea
• D. An inland body of standing water occupying a basin surrounded by land

Explanation: A lake is still water held in a land-enclosed basin.

• A. A lake containing water with a low concentration of dissolved salts
• B. A lake formed by glaciers
• C. A lake with no outlet to the sea
• D. A lake used for drinking water only

Explanation: Freshwater lakes have only small amounts of dissolved salts.

• A. A lake fed only by rain
• B. A lake containing a relatively high concentration of dissolved salts
• C. A lake with water safe for drinking
• D. A lake at high altitude

Explanation: Saline lakes accumulate salts because their water evaporates without an outlet.

• A. A lake formed in a volcanic crater
• B. A lake that freezes every winter
• C. A lake in a drainage basin with no surface-water outlet to the ocean
• D. A lake connected to the sea by a river

Explanation: Endorheic lakes sit in closed basins where water leaves only by evaporation.

• A. A lake formed by glacial erosion
• B. A lake in a volcanic caldera
• C. A curved lake formed when a river meander becomes cut off from the main channel
• D. A reservoir behind a dam

Explanation: Oxbow lakes are crescent-shaped remnants of abandoned river bends.

• A. A lake that never freezes
• B. A lake fed by hot springs
• C. A lake occupying a volcanic crater
• D. A lake formed through glacial activity, such as erosion or the damming of water by glacial deposits

Explanation: Glaciers carve basins or leave moraine dams that impound lakes.

• A. A lake occupying a volcanic crater or caldera
• B. A lake formed by a dammed river
• C. A lake in a desert basin
• D. A lake created by an earthquake

Explanation: Rain and groundwater fill the crater or caldera of a volcano to form such lakes.

• A. A natural underground aquifer
• B. A water-storage body, commonly created by constructing a dam
• C. A lake with no fish
• D. A coastal lagoon

Explanation: Reservoirs are artificial lakes built to store water for supply, power, or irrigation.

• A. The study of glaciers
• B. The study of deserts
• C. The scientific study of inland waters, including lakes
• D. The study of ocean currents

Explanation: Limnology covers lakes, rivers, and other inland water bodies.

• A. Because countries disagree on names
• B. Because lakes change size every year
• C. Because depth is never measured
• D. Because rankings differ according to surface area and water volume

Explanation: A lake can rank first by area but not by volume, so the criterion must be stated.

• A. The Caspian Sea
• B. Lake Baikal
• C. Lake Victoria
• D. Lake Superior

Explanation: The Caspian Sea has the greatest surface area of any inland lake.

• A. It contains only freshwater
• B. It is an enclosed inland water body without a natural outlet to the ocean
• C. It is smaller than most seas
• D. It is too shallow to be a sea

Explanation: With no natural connection to the ocean, the Caspian is geographically a lake.

• A. Kazakhstan, Uzbekistan, Turkmenistan, Iran, and Afghanistan
• B. Türkiye, Georgia, Armenia, Iran, and Iraq
• C. Russia, Kazakhstan, Turkmenistan, Iran, and Azerbaijan
• D. Russia, Ukraine, Romania, Bulgaria, and Türkiye

Explanation: These five states share the Caspian shoreline.
