Climate and Grasslands — 15 World Geography PYQs with Answers | UKPSC PYQ Hub

Question 1

The concept of 'Weathring' is related to?

Accepted Answer

A natural process which break Rocks into tiny particles. The concept of Weathring is related to a natural process which break rocks into tiny particles. Weathering is action of elements of weather and climate over earth materials. There are a number of processes within weathering which act either individually or together to affect the earth materials in order to reduce them to fragmental state. Weathering processes are conditioned by many complex geological, climatic, topographic and vegetative factors. Climate is of particular importance.

Question 2

In which of the following city, Mediterranean type of climate is not found?

Accepted Answer

New York. Mediterranean climate occurs around Mediterranean sea, along the west coast of continents in subtropical latitudes between 30°-40° latitudes e.g. Central California, Central Chile, along the coast in south eastern and south western Australia.

Question 3

Who made the following statement- 'Vegatation is the true index of climate'?

Accepted Answer

Koppen. Famous statement 'Vegatation is the true index of climate' was made by Koppen. The most widely used classification of climate is the empirical climate classification scheme developed by W. Koeppen. Koeppen identified a close relationship between the distribution of vegetation and climate. Geography of the World

Question 4

Koppen has used which of the following words for the climate of Great Plains of India?

Accepted Answer

Cwg. Koppen used Cwg for the climate of Great plains of India. Cwg stands for Monsoon type with dry winters, which is mostly found in most parts of the Ganga Plain, eastern Rajasthan, Assam and in Malwa Plateau. The most widely used classification of climate is the empirical climate classification scheme developed by V. Koeppen. Koeppen identified a close relationship between the distribution of vegetation and climate. He selected certain values of temperature and precipitation and related them to the distribution of vegetation and used these values for classifying the climates. It is an empirical classification based on mean annual and mean monthly temperature and precipitation data. He introduced the use of capital and small letters to designate climatic groups and types. Koeppen recognized five major climatic groups, four of them are based on temperature and one on precipitation. The capital letters : A,C, D and E delineate humid climates and B dry climates.

Question 5

As per Koppen’s classification of climate, which one of the following is the suitable description of North-East India including North Bengal?

Accepted Answer

Humid sub-tropical climate with dry winter (Cwg). The most widely used classification of climate is the empirical climate classification scheme developed by V. Koeppen. Koeppen identified a close relationship between the distribution of vegetation and climate. Koeppen recognised five major climatic groups; four of them are based on temperature and one on precipitation. Humid sub-tropical climate with dry winter (Cwg) describes the climate of North-East India including North Bengal.

Question 6

The biome with the shortest growing season is

Accepted Answer

Tundra. Tundra biome has shortest growing period. Tundra regions have long, cold winters with high winds and average temperature below freezing point for six to ten months of year. On average, only six to ten weeks of year have sufficiently warm temperatures for plant growth.

Question 7

Xerophytic plants mostly occur in

Accepted Answer

Grasslands and deserts. Xerophytic plants are mostly found in Grasslands and deserts. Xerophytic plants are adapted to live in a dry habitat.

Question 8

Which of the following biomes is most likely to be subject to desertification?

Accepted Answer

Tropical grasslands. Tropical grasslands are most likely to be subject to desertification. Tropical grasslands occur on other side of the equator and extend till the tropics. This type of vegetation grows in the areas of moderate to low amount of rainfall. The grass can grow very tall, about three to four meters in height. Savannah grasslands of Africa are of this type.
