Question
Deforestation may lead to floods. Why?
✓
Answer
Deforestation leads to floods as lesser number of trees will be available due to the deforestation. In the absence of trees and plants of the forest, the excessive amount of rainwater falling during heavy rains cannot be absorbed into forest ground. The large amount of rainwater will then suddenly flow into rivers causing the flooding of rivers.
