Total Questions: 17

1. The Savannas are most widespread in - [U.P.P.C.S. (Mains) 2011, U.P.P.C.S. (Pre) 1993]

Correct Answer: (a) Africa
Solution:Savanna is a rolling Grassland scattered with shrubs and isolated trees which can be found between a tropical rainforest and desert biome. The savannas are mainly spread, over East Africa. Savannas are also found in Brazil, Colombia, Venezuela, Beliz, Honduras and southern parts of India. Therefore, the correct answer is option (a).

2. What is the name of mid-latitude grassland in South America? [60th to 62nd B.P.S.C. (Pre) 2016]

Correct Answer: (b) Pampas
Solution:Mid-latitudes or temperate belt grasslands of South America is known as Pampas. It is spread over Argentina, Uruguay and southern parts of Brazil. Other mid-latitude grasslands are Prairie (North America), downs (Australia), etc.

A grassland ecosystem is a dry area of land dominated by grasses. Huge trees and shrubs are very rarely found in these regions, which is mainly because of the climatic conditions and other environmental factors, which do not withstand the plant's requirements.

Grasslands are also called transitional landscape. In a grassland ecosystem, the vegetation is dominated by herbs and grass. These ecosystems are mainly found in regions, where there is a scarcity of water and not enough and regular rainfall to support the growth of plants and forests.

The grassland ecosystem lies between the deserts and the forest ecosystems. Savanna grasslands and temperate grasslands are also some examples of grassland ecosystems.

3. Given below are two statements, one is labelled as Assertion (A) and other as Reason (R). [U.P. R.O./A.R.O. (Mains) 2016]

Assertion (A): The Pampas plain is the main region to me botol for cultivation in Argentina.

Reason R) : The fertile soil of Pampas and the temperate climate are very usefull for growing crops and grasses.

Choose the correct answer from the code given below.

Code:

Correct Answer: (a) Both (A) and (R) are true and (R) is the correct explanation of (A)
Solution:The Pampas of South America are a grassland biome. They are flat, fertile plains, found primarily in Argentina and extends into Uruguay and Brazil. Because of they temperate climate and rich, deep soil, most of the Pampas have been brought under cultivation and turned into croplands.

7. Which of the following temperate grasslands are found in Eurasia? [U.P.P.C.S. (Pre) 2014]

Correct Answer: (c) Steppes
Solution:The temperate grassland found in Eurasia region is Steppes. Temperate grasslands are one of the most important biomes to understand. They play an important role in our survival. They also play an important role in helping to manage climate change. Temperate grasslands are one of the two types of grassland biomes.

The other type is tropical grassland. While both types share features of being bordered by a desert and a forest, are defined by a consistent geological plane, plus have unusually rich and deep soil, temperate and tropical grasslands are very different. Temperate grasslands are located in the Northern Hemisphere.

They are also called prairies or steppes. Temperate grasslands have a distinct season pattern of growing and dormancy. Temperate grasslands can have a wide range of temperatures that occur during the year as well.

Between both types of grassland biomes they cover almost 25% of all of the Earth's landmass. Every continent has a grassland biome except one - Antarctica.

8. Which one of the following natural regions is known as 'Land of Big Games'? [U.P.P.C.S. (Pre) 2019]

Correct Answer: (d) Tropical Savanna Region
Solution:Land of Big Games is known as the Tropical Savanna region, as thousands of animals are trapped or killed each year by people from all over the world. There are two main groups of animals in the savanna, the grass-eating herbivorous animals and the flesh-eating carnivorous animals.

The herbivorous include the zebra, antelope, Giraf, deer, gazelle, elephant etc. and carnivorous animals include the lion, tiger, jackal, jaguar, leopard, hyena etc. species of reptiles and mammals includes giant Lizards, crocodiles, alligators that live together with larger rhinoceros and hippopotamus in rivers and marshy lakes.

9. The vegetation of savannah consists of grassland with scattered small trees, but extensive areas have no trees. The forest development in such areas is generally kept in check by one or more or a combination of some conditions. Which of the following are such conditions? [I.A.S. (Pre) 2021]

1. Burrowing animals and termites

2. Fire

3. Grazing herbivores

4. Seasonal rainfall

5. Soil properties

Select the correct answer using the code given below:

Correct Answer: (c) 2, 3 and 4
Solution:The main obstacle in the development of forest in the savanna grassland is the abundance of grass-grazing animals, fire in this area and seasonal rainfall. Due to seasonal rains, everything dries up in the summer in this region, due to which the development of forest is not possible in this area.
