Highest, Longest and Largest in the World: Static GK
Static GK notes on world superlatives for exams: the highest peaks, longest rivers, largest oceans, deserts, lakes, islands, countries and climate extremes.
By GK24 Editorial Team· Published · 5 min read

After the superlatives of India come the superlatives of the world, and they are asked in exactly the same one-line form: the highest peak, the longest river, the largest ocean, the deepest lake. A candidate either knows them or does not. These notes gather the world records that come from geography and therefore stay fixed, keep the disputed ones clearly marked so that a student is not caught out by a changed answer, and close with the man-made records that need refreshing before every exam.
Mountains, plateaus and deserts
Mount Everest in the Himalaya, on the border of Nepal and China, is the highest mountain in the world; the joint survey published by Nepal and China in 2020 gave its height as 8,848.86 metres. It is called Sagarmatha in Nepal and Chomolungma in Tibet. K2, also called Godwin Austen, in the Karakoram, 8,611 metres, is the second highest, and Kangchenjunga, 8,586 metres, is the third. The Andes of South America form the longest mountain range on land, running the length of the continent, while the Himalaya holds the greatest concentration of high peaks. The Tibetan plateau, called the roof of the world, is the highest and largest plateau. Antarctica is the largest desert of the world, because a desert is defined by how little precipitation it receives rather than by heat, and the Sahara in northern Africa is the largest hot desert. The Atacama in Chile is the driest desert.
| Superlative | Answer | Where |
|---|---|---|
| Highest mountain | Mount Everest, 8,848.86 m | Nepal and China border |
| Second highest mountain | K2 or Godwin Austen, 8,611 m | Karakoram range |
| Longest mountain range on land | Andes | South America |
| Highest plateau | Tibetan plateau, the roof of the world | Central Asia |
| Largest desert | Antarctica, a cold desert; Sahara among hot deserts | Antarctica; northern Africa |
| Driest place | Atacama desert | Chile |
Oceans, rivers and lakes
The Pacific is the largest and deepest ocean and the Arctic the smallest; the deepest known point on earth is the Challenger Deep in the Mariana Trench in the western Pacific, close to eleven kilometres below the surface. The Bay of Bengal is the largest bay in the world and the Gulf of Mexico the largest gulf. The Nile in Africa is conventionally taken as the longest river, about 6,650 kilometres, though several surveys argue for the Amazon; the Amazon is beyond dispute the largest river by the volume of water it carries and by the size of its basin, and it holds the largest rainforest. The Caspian Sea, enclosed by land, is the largest lake in the world, Lake Superior the largest freshwater lake by area, and Lake Baikal in Siberia the deepest lake and the one with the greatest volume of fresh water. Angel Falls in Venezuela, 979 metres, is the highest waterfall. The Great Barrier Reef off the coast of Australia is the largest coral reef system, and the Sundarbans, shared by India and Bangladesh, the largest delta and largest mangrove forest.
| Superlative | Answer |
|---|---|
| Largest and smallest ocean | Pacific; Arctic |
| Deepest point on earth | Challenger Deep, Mariana Trench, Pacific Ocean |
| Longest river | Nile, about 6,650 km, by the usual reckoning |
| Largest river by volume and basin | Amazon |
| Largest lake | Caspian Sea |
| Deepest lake | Baikal, Siberia |
| Highest waterfall | Angel Falls, Venezuela, 979 m |
| Largest bay | Bay of Bengal |
Continents, countries and islands
Asia is the largest continent by area and by population and Australia the smallest; Africa is the second largest. Russia is the largest country in the world by area, spread over two continents, and Vatican City the smallest, an enclave inside Rome. Canada has the longest coastline of any country. China and Russia each border fourteen countries, the largest number for any state. Greenland is the largest island, Indonesia the largest archipelago and the Arabian peninsula the largest peninsula. Among cities, La Paz in Bolivia is the highest seat of government in the world. The boreal forest, or taiga, that runs across northern Russia, Scandinavia and Canada is the largest forest belt on earth, and the Amazon the largest tropical rainforest.
Climate extremes and human records
Mawsynram in Meghalaya in India records the highest average rainfall in the world, with Sohra, long known as Cherrapunji, close behind. The lowest air temperature ever measured on the surface of the earth was recorded at the Vostok station in Antarctica, and the highest was recorded at Furnace Creek in Death Valley in the United States in 1913. Among structures and works of engineering, the Great Wall of China is the longest wall, Angkor Wat in Cambodia the largest religious monument, the Trans-Siberian Railway from Moscow to Vladivostok the longest railway line, about 9,289 kilometres, the Louvre in Paris the largest art museum and the Library of Congress in Washington the largest library. Mammoth Cave in the United States is the longest cave system and Son Doong in Vietnam holds the largest cave passage.
The answers that are disputed or that change
Three kinds of answers in this chapter need care. The first are disputed measurements: the length of the Nile against that of the Amazon depends on which headstream is counted, and the height of Everest was revised by the joint Nepal and China survey of 2020, so quote the figure with the survey. The second are definition-dependent: Antarctica is the largest desert only if a desert is defined by precipitation, and the Caspian is the largest lake only if an enclosed salt water body counts as a lake. A careful candidate reads the exact words of the question, which usually say hot desert, or freshwater lake, and answer accordingly. The third are man-made records, such as the tallest building, the longest bridge, the longest tunnel and the busiest airport, which shift every few years as new projects open; the Burj Khalifa in Dubai has been the tallest building since 2010, but taller towers are under construction, so check such an answer against a current source instead of an old list.
Exam Point of View
The paper asks these as single-line recall questions, so the marks depend on the exactness of the wording. Read the qualifier first. Largest desert is Antarctica, but largest hot desert is the Sahara. Largest lake is the Caspian Sea, but largest freshwater lake by area is Lake Superior and the deepest is Baikal. Longest river is the Nile by the usual reckoning, but largest river by volume and basin is the Amazon. Longest mountain range on land is the Andes, while the Himalaya has the highest peaks. Keep the top three peaks in order, Everest, K2 and Kangchenjunga, since the second and third places are asked as often as the first. Man-made records such as the tallest building and the longest bridge change every few years and should be checked afresh rather than learnt from an old list.

Practice MCQs on this topic
Which is the largest and deepest ocean in the world?
- A.Atlantic Ocean
- B.Indian Ocean
- C.Pacific Ocean
- D.Arctic Ocean
Show answer
Correct answer: C. Pacific Ocean
Explanation
The correct answer is C, Pacific Ocean. The Pacific covers a greater area than all the land on earth put together and is also the deepest ocean, holding the Challenger Deep in the Mariana Trench, the deepest known point on the planet. Its rim is ringed by volcanoes and earthquake zones, which is why it is called the Ring of Fire.
Option A, the Atlantic, is the second largest ocean and is famous for the mid-Atlantic ridge along which the sea floor is spreading. Option B, the Indian Ocean, is the third largest, the only major ocean named after a country, and the one whose monsoon winds shaped the trade of the region. Option D, the Arctic, is the smallest and shallowest of the oceans and is largely covered by ice. A candidate should remember the order by size, Pacific, Atlantic, Indian, Southern and Arctic, because the paper asks for the smallest as often as for the largest.
The deepest known point of the earth's surface, the Challenger Deep, lies in which trench?
- A.Mariana Trench
- B.Puerto Rico Trench
- C.Java Trench
- D.Peru-Chile Trench
Show answer
Correct answer: A. Mariana Trench
Explanation
The correct answer is A, Mariana Trench. The Mariana Trench lies in the western Pacific, east of the Mariana Islands, and its deepest part, the Challenger Deep, is close to eleven kilometres below sea level. Trenches of this kind form where one oceanic plate is pushed under another, a process called subduction, which is why they lie along the edges of the Pacific.
Option B, the Puerto Rico Trench, is the deepest point of the Atlantic Ocean, but it is far shallower than the Mariana. Option C, the Java or Sunda Trench, is the deepest part of the Indian Ocean and lies along the Indonesian arc. Option D, the Peru-Chile or Atacama Trench, runs along the western coast of South America, where the Nazca plate slides beneath the South American plate and raises the Andes. Each option is a real trench, so the answer rests on knowing which one holds the record.
Which river is conventionally regarded as the longest river in the world?
- A.Amazon
- B.Nile
- C.Yangtze
- D.Mississippi-Missouri
Show answer
Correct answer: B. Nile
Explanation
The correct answer is B, Nile. The Nile flows north through north-eastern Africa for about 6,650 kilometres to the Mediterranean and is the river taken as the longest in the world in almost every textbook and examination. Its two great branches, the White Nile and the Blue Nile, meet at Khartoum in Sudan.
Option A, the Amazon, is the largest river in the world by the volume of water it discharges and by the area of its basin, which holds the largest rainforest; some surveys that measure it from a different headstream in the Andes also claim it as the longest, but that reading is not the one papers expect. Option C, the Yangtze, is the longest river of Asia and flows entirely within China. Option D, the Mississippi with the Missouri, is the longest river system of North America. Read the wording carefully, since longest and largest give different answers here.
Which is the largest hot desert in the world?
- A.Gobi
- B.Kalahari
- C.Sahara
- D.Atacama
Show answer
Correct answer: C. Sahara
Explanation
The correct answer is C, Sahara. The Sahara stretches across northern Africa from the Atlantic to the Red Sea and is the largest hot desert in the world. Note the qualifier in the question: the largest desert of any kind is Antarctica, because a desert is defined by how little precipitation it receives rather than by heat, and Antarctica is therefore a cold desert.
Option A, the Gobi, lies in Mongolia and northern China and is a cold desert of the mid latitudes, not a hot one. Option B, the Kalahari, in southern Africa, is much smaller than the Sahara. Option D, the Atacama in Chile, holds a different record: it is the driest desert on earth, with places that have gone for years without measurable rain. Papers set this question in both forms, so learn the pair together: Antarctica is the largest desert and the Sahara the largest hot desert.
Angel Falls, the highest waterfall in the world, is located in which country?
- A.Brazil
- B.Venezuela
- C.Zambia
- D.Canada
Show answer
Correct answer: B. Venezuela
Explanation
The correct answer is B, Venezuela. Angel Falls drops 979 metres from the edge of a flat-topped table mountain called Auyan Tepui in the Guiana highlands of Venezuela, and is the highest uninterrupted waterfall in the world. The water falls so far that much of it turns to mist before reaching the bottom.
Option A, Brazil, shares the Iguazu Falls with Argentina, which are famous for their width and their many separate cascades rather than their height. Option C, Zambia, shares the Victoria Falls on the Zambezi with Zimbabwe, a fall known for the sheet of water it carries over a single wide ledge. Option D, Canada, shares Niagara Falls with the United States, the most visited of all waterfalls but far lower than any of the others named. The question is testing height, not fame or volume.
Which is the largest island in the world?
- A.Greenland
- B.New Guinea
- C.Borneo
- D.Madagascar
Show answer
Correct answer: A. Greenland
Explanation
The correct answer is A, Greenland. Greenland lies between the Arctic and the Atlantic, is covered almost entirely by an ice sheet and is an autonomous territory of Denmark. It is the largest island in the world. Australia is larger still but is counted as a continent rather than an island, which is the distinction the question rests on.
Option B, New Guinea, is the second largest island and is divided between Indonesia and Papua New Guinea. Option C, Borneo, is the third largest and is shared by Indonesia, Malaysia and Brunei. Option D, Madagascar, off the eastern coast of Africa, is the fourth largest and is known for species found nowhere else. Related superlatives worth learning together are Indonesia as the largest archipelago and the Arabian peninsula as the largest peninsula.
Which is the deepest lake in the world?
- A.Caspian Sea
- B.Lake Superior
- C.Lake Baikal
- D.Lake Victoria
Show answer
Correct answer: C. Lake Baikal
Explanation
The correct answer is C, Lake Baikal. Baikal lies in southern Siberia in Russia, fills a deep rift in the earth's crust and is the deepest lake in the world. It also holds a larger volume of fresh water than any other lake, roughly a fifth of all the unfrozen fresh surface water on earth, and is a World Heritage Site.
Option A, the Caspian Sea, is the largest lake in the world by area, but its water is salty and it is far shallower than Baikal. Option B, Lake Superior, one of the Great Lakes of North America, is the largest freshwater lake in the world by surface area, which is a different record. Option D, Lake Victoria in east Africa, is the largest lake of Africa and the chief reservoir of the White Nile. Each option holds some record of its own, so the qualifier deepest is what decides the answer.
Which is the longest mountain range on land?
- A.Himalaya
- B.Rocky Mountains
- C.Andes
- D.Alps
Show answer
Correct answer: C. Andes
Explanation
The correct answer is C, Andes. The Andes run down the whole western edge of South America, through seven countries from Venezuela to the southern tip of Chile and Argentina, and form the longest mountain range above sea level. They were raised where the Nazca plate is pushed beneath the South American plate, and they hold Ojos del Salado, the highest volcano in the world.
Option A, the Himalaya, holds the highest peaks in the world, including Everest, K2 in the neighbouring Karakoram and Kangchenjunga, but it is much shorter than the Andes. Option B, the Rockies, run through western North America and are long but not the longest. Option D, the Alps, are the great range of central Europe and are shorter still. Note one further distinction: the mid-ocean ridge system is longer than any of these, but it lies under the sea, which is why the question says on land.
Which is the largest bay in the world?
- A.Hudson Bay
- B.Bay of Bengal
- C.Bay of Biscay
- D.Gulf of Mexico
Show answer
Correct answer: B. Bay of Bengal
Explanation
The correct answer is B, Bay of Bengal. The Bay of Bengal is the north-eastern arm of the Indian Ocean, bounded by India, Bangladesh, Myanmar and Sri Lanka, and it is the largest bay in the world. The Ganga, the Brahmaputra, the Mahanadi, the Godavari and the Krishna all drain into it, which is why it receives such a heavy load of silt and builds large deltas along its coast.
Option A, Hudson Bay in northern Canada, is a very large body of water and is sometimes offered as the answer, but it is smaller than the Bay of Bengal. Option C, the Bay of Biscay, lies between France and Spain and is known for rough seas, not for size. Option D, the Gulf of Mexico, is the largest gulf in the world, which is a separate record; the paper sometimes places bay and gulf in the same set of options to see whether the candidate keeps the two apart.
Which is the smallest country in the world by area?
- A.Monaco
- B.Nauru
- C.Vatican City
- D.San Marino
Show answer
Correct answer: C. Vatican City
Explanation
The correct answer is C, Vatican City. Vatican City is an independent state of well under half a square kilometre lying entirely inside the city of Rome, and it is the smallest country in the world by both area and population. It is the seat of the Pope and holds St Peter's Basilica and the Sistine Chapel. At the other end of the scale, Russia is the largest country in the world by area.
Option A, Monaco, on the Mediterranean coast beside France, is the second smallest country. Option B, Nauru, an island in the Pacific, is the smallest island country and the third smallest state. Option D, San Marino, another enclave within Italy, is among the smallest and also among the oldest surviving republics. All four are genuinely tiny states, so the ranking has to be learnt rather than guessed from familiarity.
Frequently Asked Questions
Which is the longest river in the world, the Nile or the Amazon?
By the usual reckoning the Nile in Africa is the longest river, about 6,650 kilometres, and that is the answer expected in most examinations. Some surveys, measuring the Amazon from a different headstream in the Andes, place it first instead. What is not disputed is that the Amazon carries by far the greatest volume of water and drains the largest river basin in the world.
Which is the largest desert in the world?
Antarctica. A desert is defined by how little precipitation an area receives, not by its temperature, and Antarctica receives very little, so it is the largest desert on earth and a cold desert. Among hot deserts the largest is the Sahara in northern Africa. Read the wording of the question carefully, because both answers appear in the options.
What is the difference between the Caspian Sea, Lake Superior and Lake Baikal?
The Caspian Sea is landlocked and is counted as the largest lake in the world by area, although its water is salty. Lake Superior in North America is the largest freshwater lake by surface area. Lake Baikal in Siberia is the deepest lake in the world and holds the greatest volume of fresh water of any lake.
Which are the three highest mountains in the world?
Mount Everest on the Nepal and China border is the highest, measured at 8,848.86 metres by the joint survey published by the two countries in 2020. K2, also called Godwin Austen, in the Karakoram range, 8,611 metres, is the second highest, and Kangchenjunga on the Sikkim and Nepal border, 8,586 metres, is the third and the highest peak in India.
Which world records should be checked before an exam rather than memorised?
All the records created by construction. The tallest building, the longest bridge, the longest road and railway tunnel, the largest airport and the busiest airport change every few years as new projects are completed. The Burj Khalifa in Dubai has held the tallest building record since 2010, but taller towers are being built, so such answers should be taken from a current source.
