Question

Describe the roles of temperature and precipitation in determining what parts of the earth’s land are covered with:

Answer 1

Answer:

(a) Desert- In a desert environment, the temperature is relatively very high during daytime due to high absorption of sunlight and at night it again cools down. There is little or no precipitation here. This region includes the equatorial and some parts of the tropical region.

(b) Arctic tundra- This region lies in the higher latitudinal areas extending from the arctic to the extreme poles. The temperature here is extremely cold and precipitation is low. The plants and trees here are short in height.

(c) Temperate grassland- These are the mid-latitude areas covering the extensive grasslands of both the northern and the southern hemisphere. The temperature and precipitation level here are both moderate.

(d) Tropical rain forest- These are the regions that covers the vast rain forest areas in the tropical region of both the hemispheres. The temperature here is high is relatively high and high moisture content. As a result of which the rate of evaporation is high and rainfall is maximum. The region is rich in diverse trees and plants species.

(e) Temperate deciduous forest- These are the regions covering the mid latitudes that are rich in the deciduous forest. These are the dry forests comprised of various plant species. The temperature in this region is very moderate and summers are comparatively much cooler. Precipitation in this region is also quite moderate.
