Question

Forest help
A. To prevent diseases
B. To prevent rainfall
C. In soil erosion
D. To prevent floods

Answer 1

Hint: Forest is an area of land covered with trees. It is composed of plants, animals and microorganisms. Forests cover 31% of the global land area.

Complete answer:
-Forest does not have a direct correlation with the spread of disease. Hence, ‘option A’ is incorrect.
-Vegetation stores water resulting in an increase of water infiltration and storage in soil. With less runoff, more water is kept for evaporation from the soil, leaf surfaces, and transpiration of water by plants. Cloud cover increases, boosting rainfall and reducing temperatures. Hence, ‘option B’ is incorrect.
-Forest helps in preventing soil erosion. This is possible by protecting the soil from the impact of rain. They reduce the amount of water in the soil by transpiration. Their roots bind the soil to sloping land. Finally, they break the wind, preventing it from blowing soil away. Hence, ‘option C’ is incorrect.
-Forest is a natural absorber of rainwater and because of the roots of trees, it allows it to seep. Rainwater falls on leaves of trees and plants, due to which it does not fall directly on the ground. It drips slowly on the forest ground which prevents floods.

Hence, the correct answer is option (D).

Note: There are three types of forest zones which are listed below:
-Tropical forest: They grow around the equator in South America, Africa, and Southeast Asia. The temperature is stable year-round, around 27°C.
-Temperate forest: They occur in the next latitude ring, in North America, northeastern Asia, and Europe. In general, the temperature ranges from -30°C to 30°C.
-Boreal forest: They are found between 50 and 60 degrees of latitude in the sub-Arctic zone. This area contains Siberia, Scandinavia, Alaska, and Canada. Temperatures range from -40°C to 20°C.
