Question

How does deforestation reduce rainfall on one hand and leads to flood on the other?

Answer 1

Plants lose water in form of water vapor through transpiration, this water vapor helps in formation of clouds and thus in rain. So, deforestation leads to reduced rainfall.
The roots of tree regulate the flow of water and slow it down and thus, enable the soil to absorb the flowing water, thereby preventing floods. So, deforestation leads to flood.

Answer 2

Answer:

Removal of trees and plant life from a particular area for the construction of industries, agriculture and other purposes is termed as Deforestation. Photosynthesis in plant life, takes place by the absorption of CO2 from the earth’s atmosphere. When the plant life is destroyed, the Carbon Dioxide levels in the atmosphere will increase drastically leading trap of heat radiation which causes global warming. This rise in temperature will affect the water cycle. Disturbance in the water cycle will lead to a chain of events and in the end, the rainfall pattern changes and results in droughts.
