Question

How does deforestation reduce rainfall on the one hand and lead to floods on the other?

Answer 1

Deforestation means cutting down of trees or forests. We know that trees transpire and play an important role in the water cycle as it adds moisture to the air which brings rainfall. So if the number of trees decreases the process of transpiration and water cycle will be disturbed hence the rainfall will be reduced. Reduced rainfall will reduce the amount of water absorption in the soil. This soil will be dry and leads to lower water intake in the trees. This will cause soil erosion and will lead to floods.
