Question 18
Deforestation may lead to floods. Why?
Deforestation is the process of cutting down of trees and this leads to floods. In the absence of trees and plants of the forest, the excessive amount of rainwater falling during heavy rains cannot be absorbed into the forest ground. A large amount of rainwater will then suddenly flow into rivers causing flooding of rivers. Forest acts as a natural absorber of rainwater and allows it to seep. When rainwater falls, it does not fall directly on the ground. It falls on the leaves of trees and plants and then it drips slowly on the forest ground (does not stagnate) and hence prevent floods. Also, the roots of the trees absorb water and help in seeping of water into the soil. Thus helps in preventing floods.
