World Geography is one of the most dependable scoring areas in general knowledge papers. The NDA General Ability Test, the CDS General Knowledge paper, AFCAT general awareness, the UPSC Civil Services preliminary exam, SSC and state PSC exams regularly ask about the solar system, latitudes and longitudes, the layers of the Earth and the atmosphere, planetary winds, ocean currents, the longest rivers, the largest lakes and deserts, important straits and famous boundary lines.
This article brings together 100 of the most important World Geography questions on these themes. The set is divided into four parts: The Universe, the Solar System and the Earth (questions 1 to 25), the Interior of the Earth, Landforms and the Atmosphere (26 to 50), Oceans, Rivers, Lakes and Deserts (51 to 75), and Continents, Countries, Straits and Boundaries (76 to 100). It follows our Indian History, Indian Geography, Indian Polity, Indian Economy, General Science, Environment and Ecology, Indian Art and Culture, and Static GK sets, so you can revise all nine subjects in the same way.
The questions use standard facts from the NCERT geography books (Fundamentals of Physical Geography and the middle-school geography texts) and well-established world atlases. Read each question, try to recall the answer, and only then read the short explanation, which adds the related fact that examiners often turn into a second question.
The Universe, the Solar System and the Earth (Questions 1 to 25)
1. Which is the largest planet in the solar system?
Answer: Jupiter. Jupiter is a gas giant made mostly of hydrogen and helium. Its Great Red Spot is a giant storm that has been observed for centuries.
2. Which is the smallest planet and the one closest to the Sun?
Answer: Mercury. Mercury takes about 88 days to go round the Sun. Mercury and Venus are the only two planets with no natural satellite.
3. Which is the hottest planet in the solar system?
Answer: Venus. Although Mercury is closer to the Sun, the thick carbon dioxide atmosphere of Venus traps heat through a strong greenhouse effect, keeping its surface hotter than that of any other planet.
4. Which planet is called the twin of the Earth because of its similar size and mass?
Answer: Venus. Venus is also the brightest planet in the night sky and is seen as the morning star or the evening star. It rotates in the opposite direction to most planets.
5. Which planet rotates almost on its side, with its axis tilted by about 98 degrees?
Answer: Uranus. Because of this extreme tilt, each pole of Uranus has very long periods of continuous daylight and darkness during its 84-year orbit.
6. Which planet is best known for its bright ring system and is the least dense planet?
Answer: Saturn. Saturn is the second-largest planet. Its rings are made mainly of pieces of ice and rock, and its largest moon is Titan.
7. Which planet is called the Blue Planet?
Answer: The Earth. About 71 per cent of the surface of the Earth is covered by water, which makes it look blue from space. It is the only planet known to support life.
8. Which celestial body was reclassified as a dwarf planet by the International Astronomical Union in 2006?
Answer: Pluto. After this decision, the solar system is counted as having eight planets. Ceres and Eris are other well-known dwarf planets.
9. How long does sunlight take to reach the Earth?
Answer: About 8 minutes and 20 seconds. The average distance between the Sun and the Earth is about 150 million km. This distance is called one astronomical unit (AU).
10. What term is used for the true shape of the Earth?
Answer: Geoid. The Earth is slightly flattened at the poles and bulges at the Equator, so its shape is described as a geoid or an oblate spheroid.
11. By how much is the axis of the Earth tilted from the perpendicular to the plane of its orbit?
Answer: About 23.5 degrees. The axis makes an angle of about 66.5 degrees with the orbital plane. This tilt, together with the revolution of the Earth, causes the seasons and unequal lengths of day and night.
12. Around which date is the Earth closest to the Sun (perihelion)?
Answer: Around 3 January. The Earth is farthest from the Sun (aphelion) around 4 July. Seasons are caused by the tilt of the axis, not by this change in distance.
13. On which dates do the equinoxes occur, when day and night are nearly equal all over the world?
Answer: Around 21 March and 23 September. On the equinoxes the Sun is directly overhead at the Equator. In the Northern Hemisphere, 21 March is the spring (vernal) equinox and 23 September the autumnal equinox.
14. Which day is the longest day in the Northern Hemisphere?
Answer: 21 June, the summer solstice. On this day the Sun is overhead at the Tropic of Cancer. The shortest day in the Northern Hemisphere is around 22 December, when the Sun is overhead at the Tropic of Capricorn.
15. At which latitude is the Tropic of Capricorn located?
Answer: About 23.5 degrees South. The Tropic of Cancer lies at about 23.5 degrees North. The belt between the two tropics is called the Torrid Zone, because the Sun is overhead at least once a year everywhere within it.
16. At which latitude is the Arctic Circle located?
Answer: About 66.5 degrees North. North of the Arctic Circle there is at least one day of continuous daylight in summer and one day of continuous night in winter. The Antarctic Circle lies at about 66.5 degrees South.
17. Through which place does the Prime Meridian (0 degree longitude) pass?
Answer: Greenwich, near London. Greenwich was accepted as the Prime Meridian at the International Meridian Conference held in Washington in 1884. Longitudes are measured up to 180 degrees east and west of it.
18. By how many minutes does local time change for every one degree of longitude?
Answer: Four minutes. The Earth rotates through 360 degrees in 24 hours, which is 15 degrees in one hour or one degree in four minutes. Places to the east are ahead in time.
19. Which imaginary line, roughly along the 180 degree meridian, marks the change of date?
Answer: The International Date Line. A traveller crossing the line from east to west gains a day (the date moves forward), and one crossing from west to east repeats a day. The line zigzags to avoid dividing land and island groups.
20. Which country has the largest number of time zones within its continuous territory?
Answer: Russia. Russia stretches across 11 time zones from Kaliningrad in the west to Kamchatka in the east. It is also the largest country in the world by area.
21. What is the outermost layer of the Sun’s atmosphere, seen as a glowing halo during a total solar eclipse, called?
Answer: The corona. The visible surface of the Sun is the photosphere. India’s Aditya-L1 mission, launched in 2023, studies the Sun, including its corona, from the L1 Lagrange point.
22. On which phase of the Moon can a solar eclipse occur?
Answer: New moon (amavasya). A solar eclipse occurs when the Moon comes between the Sun and the Earth. A lunar eclipse occurs on a full moon night, when the Earth comes between the Sun and the Moon.
23. To which galaxy does our solar system belong?
Answer: The Milky Way. The Milky Way is a spiral galaxy. The Andromeda Galaxy is the nearest large spiral galaxy to it.
24. Which is the nearest star to the Earth after the Sun?
Answer: Proxima Centauri. It is about 4.2 light years away and belongs to the Alpha Centauri star system. Sirius, the Dog Star, is the brightest star in the night sky.
25. A light year is a unit of which quantity?
Answer: Distance. A light year is the distance light travels in one year in a vacuum, which is about 9.46 trillion km. It is a unit of distance, not of time.
Interior of the Earth, Landforms and the Atmosphere (Questions 26 to 50)
26. What is the innermost layer of the Earth called?
Answer: The inner core. The inner core is solid and is made mainly of nickel and iron, which is why the core is called NIFE. The outer core is liquid.
27. What is the boundary between the crust and the mantle called?
Answer: The Mohorovicic discontinuity (Moho). It is named after the Croatian seismologist Andrija Mohorovicic. The boundary between the mantle and the core is called the Gutenberg discontinuity.
28. Which earthquake waves cannot travel through liquids?
Answer: S-waves (secondary waves). P-waves (primary waves) travel through solids, liquids and gases. The fact that S-waves do not pass through the outer core shows that the outer core is liquid.
29. Which is the largest tectonic plate on the Earth?
Answer: The Pacific Plate. It lies mostly under the Pacific Ocean. Most of the major plates, such as the Eurasian, African and North American plates, carry both continents and ocean floor.
30. Which ocean is ringed by the belt of volcanoes and earthquakes called the Ring of Fire?
Answer: The Pacific Ocean. The Ring of Fire follows the plate boundaries around the Pacific and contains most of the world’s active volcanoes. Japan, Indonesia, the Philippines and Chile lie on it.
31. Who put forward the theory of continental drift in 1912?
Answer: Alfred Wegener. Wegener said all continents were once joined in a single supercontinent called Pangaea, surrounded by a huge ocean called Panthalassa. The later theory of plate tectonics explained how the continents move.
32. Which is the highest mountain peak in the world?
Answer: Mount Everest. It lies on the border of Nepal and China (Tibet). In 2020, Nepal and China jointly announced its height as 8,848.86 m. In Nepal it is called Sagarmatha.
33. Which is the longest mountain range on land?
Answer: The Andes. The Andes run for about 7,000 km along the western side of South America, through countries such as Peru, Bolivia, Chile and Argentina.
34. Which is the highest peak of Africa?
Answer: Mount Kilimanjaro. Kilimanjaro is a dormant volcano in Tanzania, about 5,895 m high. Its summit is snow-capped even though it lies close to the Equator.
35. Which is the highest peak in Europe?
Answer: Mount Elbrus. Elbrus lies in the Caucasus Mountains in Russia and is about 5,642 m high. Mont Blanc, on the border of France and Italy, is the highest peak of the Alps.
36. Which is the highest peak of South America and of the Andes?
Answer: Aconcagua. Aconcagua, in Argentina, is about 6,961 m high. It is the highest mountain outside Asia.
37. Which mountain knot of Central Asia is traditionally known as the Roof of the World?
Answer: The Pamir Knot. Several great ranges, such as the Hindu Kush, Karakoram, Kunlun and Tien Shan, radiate from the Pamirs. The name Roof of the World is also often used for the Tibetan Plateau, the largest and highest plateau in the world.
38. The Himalayas, Alps, Andes and Rockies are examples of which type of mountains?
Answer: Young fold mountains. Fold mountains are formed when layers of rock are compressed and folded where tectonic plates collide. The Aravallis in India are among the oldest fold mountains in the world.
39. The Black Forest of Germany and the Vosges of France are examples of which type of mountains?
Answer: Block mountains. Block mountains are formed when large blocks of land rise between faults. The uplifted block is called a horst and a sunken block between faults is called a graben, or rift valley.
40. Which is the lowest point on land on the Earth’s surface?
Answer: The shore of the Dead Sea. The Dead Sea, between Jordan and Israel and the West Bank, lies about 430 m below sea level. Its water is so salty that people float on it easily.
41. In which layer of the atmosphere does almost all weather occur?
Answer: The troposphere. It is the lowest layer, about 8 km thick at the poles and about 18 km at the Equator. Temperature falls by about 6.5 degrees Celsius for every 1 km of height, which is called the normal lapse rate.
42. Which layer of the atmosphere, just above the troposphere, is preferred for flying jet aircraft because it is free from clouds and storms?
Answer: The stratosphere. The stratosphere extends up to about 50 km and contains the ozone layer. Temperature rises with height in this layer because ozone absorbs ultraviolet radiation.
43. Which part of the upper atmosphere reflects radio waves back to the Earth?
Answer: The ionosphere. The ionosphere contains electrically charged particles (ions) and lies within the thermosphere. It makes long-distance radio communication possible.
44. In which layer of the atmosphere do most meteors burn up?
Answer: The mesosphere. The mesosphere lies above the stratosphere, up to about 80 km. It is the coldest layer of the atmosphere.
45. What are the permanent winds that blow from the subtropical high-pressure belts towards the equatorial low-pressure belt called?
Answer: The trade winds. They blow from the north-east in the Northern Hemisphere and from the south-east in the Southern Hemisphere. Sailing ships used them for trade, which gave them their name.
46. What are the strong westerly winds at about 40 degrees South latitude called?
Answer: The Roaring Forties. Because there is very little land in the Southern Hemisphere to slow them down, the westerlies blow strongly there. At about 50 and 60 degrees South they are called the Furious Fifties and the Shrieking Sixties.
47. Which force deflects winds to the right in the Northern Hemisphere and to the left in the Southern Hemisphere?
Answer: The Coriolis force. It is caused by the rotation of the Earth. The deflection is described by Ferrel’s law and is zero at the Equator.
48. Which warm, dry local wind blows down the eastern slopes of the Rocky Mountains and is called the snow eater?
Answer: The Chinook. The Chinook melts snow quickly and keeps grasslands free of snow in winter, which helps cattle grazing. A similar wind in the Alps is called the Foehn.
49. Which hot, dusty local wind blows from the Sahara towards Italy and other Mediterranean countries?
Answer: The Sirocco. The Sirocco often brings red dust and is sometimes called blood rain when it mixes with rain. The Mistral is a cold wind that blows down the Rhone valley in France.
50. What is the belt of calm and light winds near the Equator called?
Answer: The Doldrums. The Doldrums lie in the equatorial low-pressure belt, where the trade winds of both hemispheres meet. The calm belts at about 30 degrees North and South are called the Horse Latitudes.
Oceans, Rivers, Lakes and Deserts (Questions 51 to 75)
51. Which is the largest and deepest ocean in the world?
Answer: The Pacific Ocean. It covers about one-third of the Earth’s surface. The name Pacific, meaning peaceful, was given by the explorer Ferdinand Magellan.
52. Which is the deepest known point in the oceans?
Answer: The Challenger Deep in the Mariana Trench. The Mariana Trench lies in the western Pacific Ocean, east of the Philippines. The Challenger Deep is nearly 11,000 m deep.

56. Which warm ocean current keeps the ports of north-western Europe, such as those of Norway, ice-free in winter?
Answer: The Gulf Stream and its extension, the North Atlantic Drift. The Gulf Stream starts in the Gulf of Mexico and flows along the eastern coast of the USA before crossing the Atlantic as the North Atlantic Drift.
57. Which cold ocean current flows along the coast of Peru and supports rich fishing grounds?
Answer: The Humboldt Current (Peru Current). Upwelling of cold, nutrient-rich water along this coast supports plankton and fish. During El Nino, warm water weakens this upwelling and hurts the fishing industry.
58. Where do the warm Gulf Stream and the cold Labrador Current meet to form one of the world’s richest fishing grounds?
Answer: The Grand Banks, off Newfoundland. The mixing of warm and cold water helps plankton to grow, which attracts fish. It also produces thick fog in the area.
59. Which sea is generally given as the saltiest of the open seas?
Answer: The Red Sea. High evaporation in a hot, dry region and very little inflow of river water raise its salinity to about 40 parts per thousand, compared with an average of about 35 for the oceans.
60. Which is generally regarded as the longest river in the world?
Answer: The Nile. The Nile is about 6,650 km long and flows north through north-eastern Africa into the Mediterranean Sea. Its two main headstreams, the White Nile and the Blue Nile, meet at Khartoum in Sudan.
61. Which river carries the largest volume of water in the world?
Answer: The Amazon. The Amazon in South America also has the largest drainage basin in the world. It flows through the largest tropical rainforest on the Earth.
62. Which river crosses the Equator twice?
Answer: The Congo (Zaire) River. The Congo flows through central Africa into the Atlantic Ocean. It is the deepest river in the world and has the second-largest flow after the Amazon.
63. Which river crosses the Tropic of Capricorn twice?
Answer: The Limpopo. The Limpopo flows through southern Africa and enters the Indian Ocean in Mozambique. In India, the Mahi river crosses the Tropic of Cancer twice.
64. On which river is the Three Gorges Dam built?
Answer: The Yangtze. The Yangtze (Chang Jiang) is the longest river in Asia. The Three Gorges Dam in China is the world’s largest hydroelectric power station by installed capacity.
65. Which river is known as China’s Sorrow?
Answer: The Huang He (Yellow River). It got this name because of its frequent and destructive floods. It carries huge amounts of yellow loess silt, which gives it its colour and name.
66. Which river of Europe flows through the largest number of countries?
Answer: The Danube. The Danube flows through 10 countries and four capitals: Vienna, Bratislava, Budapest and Belgrade. It rises in the Black Forest of Germany and enters the Black Sea.
67. Which is the largest lake in the world by area?
Answer: The Caspian Sea. It is a saltwater lake between Europe and Asia, bordered by Russia, Kazakhstan, Turkmenistan, Iran and Azerbaijan.
68. Which is the largest freshwater lake in the world by area?
Answer: Lake Superior. Lake Superior is the largest of the five Great Lakes of North America and lies on the border of the USA and Canada.
69. Which is the deepest lake in the world?
Answer: Lake Baikal. Lake Baikal in Siberia, Russia, is more than 1,600 m deep. It holds about one-fifth of the world’s unfrozen surface fresh water, the largest volume of any freshwater lake.
70. Which lake, on the border of Peru and Bolivia, is known as the highest navigable lake in the world?
Answer: Lake Titicaca. It lies at a height of about 3,800 m in the Andes. Lake Victoria in Africa, by contrast, is the largest lake of Africa and a source of the White Nile.
71. Which is the highest uninterrupted waterfall in the world?
Answer: Angel Falls. Angel Falls in Venezuela drops about 979 m in total, with a single uninterrupted fall of about 807 m. It lies in Canaima National Park.
72. On which river are the Victoria Falls located?
Answer: The Zambezi. The Victoria Falls lie on the border of Zambia and Zimbabwe. The local name, Mosi-oa-Tunya, means the smoke that thunders.
73. Which is the largest hot desert in the world?
Answer: The Sahara. The Sahara covers much of northern Africa. If cold deserts are included, Antarctica is the largest desert in the world.
74. Which desert in Chile is considered one of the driest places on the Earth?
Answer: The Atacama Desert. The Atacama lies in the rain shadow of the Andes, and the cold Humboldt Current off the coast further reduces rainfall.
75. In which country does the larger part of the Kalahari Desert lie?
Answer: Botswana. The Kalahari also extends into Namibia and South Africa. It is home to the San people, also called Bushmen.
Continents, Countries, Straits and Boundaries (Questions 76 to 100)

100. Which country is known as the Land of a Thousand Lakes?
Answer: Finland. Finland has tens of thousands of lakes, many formed by glaciers during the Ice Age. Its capital is Helsinki.
Quick Revision Tips
- Learn the planets in order from the Sun (Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune) and attach one record to each: smallest, hottest, Blue Planet, Red Planet, largest, ringed and least dense, tilted on its side and farthest.
- Draw the Earth with its main latitudes marked: the Equator, the two tropics at about 23.5 degrees and the two polar circles at about 66.5 degrees. Add the dates when the Sun is overhead: 21 March and 23 September at the Equator, 21 June at the Tropic of Cancer and 22 December at the Tropic of Capricorn.
- Remember the layers of the atmosphere from the ground upwards (troposphere, stratosphere, mesosphere, thermosphere and exosphere) with one fact each: weather, ozone and jet aircraft, meteors, and radio waves in the ionosphere.
- Revise the records of the world in one table: longest river (Nile), largest river by volume (Amazon), largest lake (Caspian Sea), largest freshwater lake (Superior), deepest lake (Baikal), largest hot desert (Sahara), highest peak (Everest) and deepest point (Challenger Deep).
- Practise straits, canals and boundary lines on a blank world map, because questions often ask which two water bodies or countries they connect or separate. Mark Gibraltar, Malacca, Bering, Hormuz, Suez and Panama, together with the McMahon, Durand and Radcliffe Lines.
Conclusion
World Geography questions are easy to score once you link each fact to a place on the map. If you can recall these 100 questions, you will have covered a large share of the solar system, landforms, climate, oceans, rivers and political geography asked in NDA, CDS, AFCAT, UPSC, SSC and state PSC papers. Keep an atlas open while you revise, test yourself on blank maps every week, and come back to the sections where you made mistakes.
FAQs
1. What does World Geography cover in competitive exams?
It covers the universe and the solar system, the motions of the Earth, latitudes and longitudes, the interior of the Earth, landforms, the atmosphere and winds, ocean currents, rivers, lakes and deserts, and the political geography of continents, countries, straits and boundary lines.
2. How many geography questions are asked in NDA, CDS and AFCAT?
The number changes from paper to paper, so it is better not to prepare for a fixed count. Geography appears regularly in the NDA General Ability Test, the CDS General Knowledge paper and AFCAT general awareness, and World Geography is a regular part of it.
3. Which books are best for World Geography?
The NCERT geography books, especially Fundamentals of Physical Geography for Class 11 and the middle-school geography texts, are the best base. Use a good school atlas alongside them to locate every place you read about.
4. How can I remember straits and boundary lines?
Mark them on a blank world map and write the two water bodies or countries on either side of each one. Revising them on a map is much easier than memorising a list, and it helps with map-based questions too.
5. How should I revise these 100 World Geography questions?
Read one section at a time, cover the answers and test yourself, then mark the questions you got wrong. Revise the marked questions again after two or three days, and use the Quick Revision Tips for last-minute revision before the exam.
