World Climatic Regions and Grasslands: Types and Exam Facts
Complete notes on world climatic regions and grasslands: Koppen groups, equatorial to tundra belts, their vegetation, and the named grasslands of each continent.
By GK24 Editorial Team· Published · 4 min read

The earth receives unequal heat from the sun, and the winds and ocean currents then carry that heat unevenly, so the same latitude on a western coast and an eastern coast can hold two different climates. Geographers therefore group the world into climatic regions: belts in which temperature, rainfall and the natural vegetation repeat themselves. Examiners like the chapter because each belt carries a name, a latitude, a rainfall figure and a vegetation type that can be paired in a matching question, and because the world grasslands give a long list of names that can be asked against their countries.
How climates are classified
The classification every exam follows is the one Wladimir Koppen, a German climatologist, built in 1918 and revised in 1936. He used mean monthly temperature and mean monthly rainfall, because these decide what grows, and gave every region a code of letters. The first capital letter is the group: A for tropical, B for dry, C for warm temperate, D for cold snow forest, E for polar and H for highland. The second letter describes the rainfall, such as f for rain in every month, m for monsoon, s for a dry summer and w for a dry winter, and a third small letter grades the heat. Two temperature lines do most of the work: the warmest month above 10 degrees Celsius separates the polar E climates from the rest, and the coldest month above 18 degrees Celsius marks the tropical A climates. An older scheme by Greek scholars simply cut the earth into a torrid, two temperate and two frigid zones by the tropics and the polar circles, and a question sometimes asks for that too.
The climatic regions at a glance
| Region | Koppen code | Where | Vegetation |
|---|---|---|---|
| Equatorial | Af | 0 to 10 degrees, Amazon, Congo, Indonesia | Selvas, evergreen hardwood |
| Tropical monsoon | Am | India, Myanmar, South East Asia | Deciduous forest, bamboo |
| Savanna or Sudan type | Aw | 5 to 20 degrees, Sudan belt, Llanos, Campos | Tall elephant grass with thorny trees |
| Hot desert | BWh | 20 to 30 degrees, western margins | Cactus, date palm, xerophytes |
| Steppe or temperate grassland | BS | Interiors of continents | Short nutritious grass |
| Mediterranean | Cs | 30 to 45 degrees, western margins | Citrus orchards, olive, cork oak |
| China type | Cfa and Cwa | 25 to 45 degrees, eastern margins | Mixed forest, tea and rice |
| British or marine west coast | Cfb | 45 to 60 degrees, western margins | Temperate deciduous forest |
| Taiga or Siberian type | Df and Dw | 50 to 70 degrees north only | Coniferous softwood on podzol soil |
| Tundra | ET | Beyond 70 degrees | Mosses, lichens, no trees |
| Ice cap | EF | Greenland and Antarctica | None |
The hot and the dry belts
The equatorial belt is hot and wet in every month, with two rainfall maxima near the equinoxes and heavy convectional rain in the afternoon, which is why its forest is called the selvas and its day is said to have no seasons, only a morning and a storm. The savanna belt lies on both sides of it and has a sharply dry season, so its grass grows tall and coarse and its trees shed leaves; this is the land of the African big game. The hot deserts sit under the descending air of the subtropical high on the western margins of continents, where cold currents and offshore trade winds keep the rain away. The Sahara is the largest hot desert on earth, the Atacama of Chile and Peru the driest, and the Thar, Arabian, Kalahari and Sonoran complete the list. Mid latitude deserts such as the Gobi, Patagonian and Turkestan deserts are dry instead because they are far from the sea or stand in a rain shadow, and they are cold in winter.
The temperate belts
The Mediterranean region is the one belt in the world with a dry summer and a wet winter, because the westerlies reach it only in winter when the pressure belts shift towards the equator; its fruit orchards gave it the name of the orchard lands of the world. The China type on the eastern margins is its mirror, with rain in summer from the monsoon and from tropical cyclones. The British type further polewards gets rain in all seasons from the westerlies and has the smallest range of temperature. Deep inside the continents the steppe climate takes over, too dry for trees and ideal for short grass, and this is where the world grasslands lie.
Grasslands of the world
Tropical grasslands are wetter and taller; temperate grasslands are short, nutritious and the great wheat and cattle lands.
| Grassland | Region or country | Type |
|---|---|---|
| Savanna | Sudan belt of Africa | Tropical |
| Llanos | Orinoco basin, Venezuela and Colombia | Tropical |
| Campos | Brazilian highlands | Tropical |
| Prairies | United States and Canada | Temperate |
| Pampas | Argentina and Uruguay | Temperate |
| Velds | South Africa | Temperate |
| Downs | Australia | Temperate |
| Steppes | Central Asia and Russia | Temperate |
| Pustaz | Hungary | Temperate |
| Canterbury | New Zealand | Temperate |
Grasslands of India
India has no grassland of that scale, but the high meadows of the Himalayas above the tree line are called bugyal in Uttarakhand and marg in Kashmir, which is why the hill stations there are named Gulmarg and Sonmarg. The terai belt at the foot of the hills carries tall elephant grass that shelters the one horned rhinoceros, and the dry grass and scrub of the Deccan and Rajasthan is the home of the blackbuck, the wolf and the great Indian bustard.
Exam Point of View
The commonest question is a matching one between a grassland and its country, and the trap is the pair of South Africa and Australia, where the Velds are African and the Downs Australian. The second favourite is the Koppen letter: Af for equatorial, Aw for savanna, Cs for Mediterranean and ET for tundra. Expect a question on the only belt with winter rain, which is the Mediterranean, and one on the belt with no trees, which is the tundra. Deserts are asked by superlative, the Sahara as the largest hot desert and the Atacama as the driest, and by cause, with the hot deserts on the western margins under the trade winds and the Gobi and Patagonia dry by continentality and rain shadow. Remember that the taiga has no southern counterpart, that selvas is equatorial forest and not grassland, and that bugyal and marg are Indian mountain meadows.

Practice MCQs on this topic
In which of the following countries is the Pampas grasslands situated?
- A.Argentina
- B.Brazil
- C.Chile
- D.Ecuador
Show answer
Correct answer: A. Argentina
Explanation
The correct answer is A, Argentina. The Pampas are the temperate grasslands of the lower Parana and Plata basin, spread mainly over Argentina and extending into Uruguay. Short nutritious grass and a deep fertile soil made them a great wheat and cattle land, and the herdsman of the Pampas is called a gaucho. Option B, Brazil, is wrong because the grassland of the Brazilian highlands is the Campos, which is tropical and taller. Option C, Chile, is wrong because Chile is a long, narrow country of the western margin whose landscapes are the Atacama desert in the north, a Mediterranean belt in the middle and cold forests in the south, not a grassland. Option D, Ecuador, is wrong because it straddles the equator and carries equatorial forest and high Andean paramo, not temperate grass. Remember the pair of South America, with Pampas in Argentina and Campos in Brazil.
Which of the following statements is NOT correct about the tundra type of vegetation?
- A.Small shrubs are a part of this vegetation
- B.Moss and lichens are found here
- C.The growth of natural vegetation is limited here
- D.It is found in a temperate region
Show answer
Correct answer: D. It is found in a temperate region
Explanation
The correct answer is D, because the tundra is not a temperate region at all. It is the polar belt beyond about 70 degrees latitude, where the warmest month stays below 10 degrees Celsius and the subsoil remains frozen as permafrost, so Koppen codes it ET in his polar E group. Option A is correct and therefore not the answer, since dwarf shrubs, stunted birch and willow do grow in the brief summer. Option B is correct as well, because mosses and lichens are the typical tundra plants and the reindeer feeds on them. Option C is correct too, as the short growing season, the frozen subsoil and the thin soil keep growth low and treeless. The statement in D confuses the tundra with the temperate deciduous forests of the middle latitudes, which is the trap the paper setter wanted.
In which of the following continents is the Gobi desert located?
- A.Europe
- B.North America
- C.Asia
- D.Africa
Show answer
Correct answer: C. Asia
Explanation
The correct answer is C, Asia. The Gobi lies in central Asia, across southern Mongolia and northern China, and it is a cold mid latitude desert: it is dry not because of the trade winds but because it is far from the sea and the Himalayan and other ranges cut off the monsoon, and its winters are bitterly cold. Option A, Europe, is wrong because Europe has no true desert; its driest lands are the steppes near the Caspian. Option B, North America, is wrong because the deserts there are the Sonoran, Mojave, Chihuahuan and the Great Basin. Option D, Africa, is wrong because the African deserts are the Sahara in the north and the Kalahari and Namib in the south. Pair the cold deserts in your memory: Gobi in Asia, Patagonia in South America and Turkestan in central Asia.
Consider the following pairs and choose the correct option.
| Region | Grassland |
|---|---|
| North America | Prairie |
| South Africa | Down |
| Central Asia | Steppe |
| Australia | Veld |
How many pairs given above are correctly matched?
- A.Only 1 pair
- B.Only 2 pairs
- C.Only 3 pairs
- D.All four pairs
Show answer
Correct answer: B. Only 2 pairs
Explanation
The correct answer is B, only 2 pairs. North America and Prairie is right, as the prairies are the temperate grasslands of the United States and Canada and the granary of the world. Central Asia and Steppe is right as well, since the steppes run from Ukraine and Russia across Kazakhstan into Mongolia. The other two pairs have been swapped: the grassland of South Africa is the Veld, and the grassland of Australia is the Downs, so South Africa and Down is wrong and Australia and Veld is wrong. Only two pairs are therefore correct. Options A and C give the wrong count, and option D is wrong because two pairs are interchanged. This swap of Veld and Downs is the single commonest trap in questions on world grasslands, so fix it as Veld for Africa and Downs for Australia.
The vast meadows in the high elevation ranges of the Himalayas are called ________.
- A.Bhabar
- B.Maru
- C.Bugyal
- D.Green meadows
Show answer
Correct answer: C. Bugyal
Explanation
The correct answer is C, Bugyal. Bugyal is the local name in Uttarakhand for the alpine meadows that lie above the tree line in the Greater Himalayas, used by shepherds for summer grazing; in Kashmir the same meadows are called marg, which gives the names Gulmarg and Sonmarg. Option A, Bhabar, is wrong because the bhabar is the narrow belt of coarse pebbles at the foot of the Shiwaliks where the streams disappear underground. Option B, Maru, is wrong because maru means desert and Marusthali is the name of the Thar. Option D is wrong because green meadows is only a translation and not the term geography uses. Note the pair the paper setter wants: bugyal in Uttarakhand and marg in Kashmir, both alpine meadows and not grasslands of the plains.
In the Koppen classification of climates, which code stands for the equatorial or tropical rainforest climate?
- A.Aw
- B.Af
- C.Cs
- D.ET
Show answer
Correct answer: B. Af
Explanation
The correct answer is B, Af. In Koppen scheme the capital A stands for the tropical group, in which the coldest month is still above 18 degrees Celsius, and the small f stands for rain in every month of the year, so Af is the equatorial or tropical rainforest climate of the Amazon, the Congo and Indonesia. Option A, Aw, is wrong because w marks a dry winter, which gives the savanna or Sudan type climate. Option C, Cs, is wrong because C is the warm temperate group and s marks a dry summer, so Cs is the Mediterranean climate. Option D, ET, is wrong because E is the polar group and T stands for tundra, the treeless belt whose warmest month stays below 10 degrees Celsius. Learn the letters as groups first and the small rainfall letters second.
Which one of the following is the only climatic region of the world that receives its rainfall mainly in winter?
- A.Equatorial region
- B.Monsoon region
- C.Mediterranean region
- D.Savanna region
Show answer
Correct answer: C. Mediterranean region
Explanation
The correct answer is C, the Mediterranean region. It lies on the western margins of continents between about 30 and 45 degrees latitude, and the wind belts shift with the sun: in winter the rain bearing westerlies move towards the equator and reach it, while in summer the dry descending air of the subtropical high sits over it. The result is a wet winter and a dry summer, a combination found nowhere else, and it suits citrus, olive and grape. Option A is wrong because the equatorial belt gets convectional rain in every month. Option B is wrong because the monsoon lands get their rain in summer, from the sea bound south west winds. Option D is wrong because the savanna also gets summer rain, when the equatorial low pressure belt moves over it, and has a dry winter.
The Llanos and the Campos are examples of which type of natural vegetation?
- A.Temperate grasslands
- B.Tropical grasslands
- C.Coniferous forests
- D.Mediterranean scrub
Show answer
Correct answer: B. Tropical grasslands
Explanation
The correct answer is B, tropical grasslands. The Llanos are the grasslands of the Orinoco basin in Venezuela and Colombia and the Campos those of the Brazilian highlands, and both lie in the savanna belt, where a hot wet season alternates with a sharply dry one and the grass grows tall and coarse with scattered thorny trees. Option A is wrong because the temperate grasslands of South America are the Pampas of Argentina, with short nutritious grass. Option C is wrong because coniferous forest is the taiga of the cold northern latitudes, far from these basins. Option D is wrong because Mediterranean scrub grows in the dry summer belts of the western margins, such as central Chile, and consists of hard leaved evergreen shrubs. Group the tropical grasslands as Savanna in Africa, Llanos in Venezuela and Campos in Brazil.
Which of the following grassland and country pairs is correctly matched?
- A.Pustaz and New Zealand
- B.Canterbury and Hungary
- C.Velds and South Africa
- D.Downs and Argentina
Show answer
Correct answer: C. Velds and South Africa
Explanation
The correct answer is C, Velds and South Africa. The Velds are the temperate grasslands of the high plateau of South Africa, where maize and cattle farming and the gold mining of the Witwatersrand go together. Option A is wrong because the Pustaz is the grassland of Hungary, in the middle Danube basin. Option B is wrong because Canterbury is the grassland of the South Island of New Zealand, famous for sheep. Option D is wrong on both counts, because the Downs are the grasslands of Australia, especially the Murray Darling basin, and the grassland of Argentina is the Pampas. The question works entirely on swapped pairs, so memorise the list as one chain: Prairies in North America, Pampas in Argentina, Velds in South Africa, Downs in Australia, Steppes in Eurasia, Pustaz in Hungary and Canterbury in New Zealand.
Why is the taiga or coniferous forest belt absent in the southern hemisphere?
- A.The southern hemisphere is too warm at every latitude
- B.Almost no land lies in the 50 to 70 degree latitudes of the south
- C.Conifers cannot grow in the southern hemisphere
- D.The southern hemisphere has no mountains
Show answer
Correct answer: B. Almost no land lies in the 50 to 70 degree latitudes of the south
Explanation
The correct answer is B. The taiga is the belt of coniferous softwood forest between about 50 and 70 degrees latitude, and in the southern hemisphere that belt is almost entirely ocean: only the narrow tail of South America and a few islands reach it, which is far too little land for a continuous forest belt. Option A is wrong because the south is not too warm; the latitude is cool enough, there is simply no land there. Option C is wrong because conifers do grow in the south, in the mountains of Chile, New Zealand and Australia, only not as a vast belt. Option D is wrong because the southern hemisphere has great ranges such as the Andes and the Drakensberg; mountains are not the reason. This asymmetry of land and water is also why the south has a smaller annual range of temperature.
The hot deserts of the world such as the Sahara and the Kalahari are mainly found in which position on a continent?
- A.On the eastern margins near the equator
- B.On the western margins between 20 and 30 degrees latitude
- C.In the interiors beyond 60 degrees latitude
- D.Along the polar circles
Show answer
Correct answer: B. On the western margins between 20 and 30 degrees latitude
Explanation
The correct answer is B. Hot deserts lie on the western margins of continents roughly between 20 and 30 degrees north and south, under the descending dry air of the subtropical high pressure belt. The trade winds there blow from the land to the sea, so they carry no moisture inland, and cold currents such as the Canary, Benguela and Peru currents chill the air over the coast and stop it from rising, which is why fog is common but rain is not. Option A is wrong because the eastern margins in low latitudes get heavy rain from the trade winds and the monsoon. Option C is wrong because the dry lands of the high interiors, such as the Gobi, are cold deserts and lie well below 60 degrees. Option D is wrong because the polar belts are cold deserts of ice, not hot deserts.
The dense evergreen equatorial forest of the Amazon basin is known by which name?
- A.Taiga
- B.Selvas
- C.Steppes
- D.Campos
Show answer
Correct answer: B. Selvas
Explanation
The correct answer is B, Selvas. Selvas is the name given to the equatorial rainforest of the Amazon basin, a multi storeyed evergreen forest of hardwoods such as mahogany, ebony and rosewood, with so many species mixed together that commercial logging of a single kind is difficult. Option A, Taiga, is wrong because the taiga is the coniferous softwood forest of the cold northern latitudes of Eurasia and North America. Option C, Steppes, is wrong because the steppes are the temperate grasslands of Eurasia, not forest at all. Option D, Campos, is wrong because the Campos is the tropical grassland of the Brazilian highlands, which lies in the same country but outside the equatorial basin. Keep the three Amazonian words apart: Selvas is the forest, Campos the grassland and the Llanos the grassland of the Orinoco.
Frequently Asked Questions
Who gave the classification of world climatic regions used in exams?
Wladimir Koppen, a German climatologist, published it in 1918 and revised it in 1936. He used mean monthly temperature and rainfall because they decide the natural vegetation, and gave each region a code of letters such as Af for equatorial and Cs for Mediterranean.
Which grassland is found in which country?
Prairies are in the United States and Canada, Pampas in Argentina and Uruguay, Velds in South Africa, Downs in Australia, Steppes in Central Asia and Russia, Pustaz in Hungary and Canterbury in New Zealand. Among tropical grasslands, Llanos lies in the Orinoco basin of Venezuela and Campos on the Brazilian highlands.
Why does the Mediterranean region get rain in winter?
The pressure and wind belts shift with the apparent movement of the sun. In winter the westerlies move towards the equator and bring rain bearing depressions to the 30 to 45 degree western margins, while in summer the dry subtropical high sits over the same belt. That is why its summer is dry and its winter wet.
Which is the largest hot desert and which is the driest desert?
The Sahara in northern Africa is the largest hot desert in the world. The Atacama, along the coast of Chile and Peru, is the driest, because the cold Peru current and the offshore winds give it almost no rain.
Why is the taiga found only in the northern hemisphere?
The taiga is the coniferous forest belt of 50 to 70 degrees latitude. In the southern hemisphere that latitude is almost entirely ocean, with only the narrow tip of South America, so no comparable belt of coniferous forest can form there.
What are the high meadows of the Himalayas called?
They are called bugyal in Uttarakhand and marg in Kashmir, which is why places there are named Gulmarg and Sonmarg. These alpine meadows lie above the tree line and are used for summer grazing.
