Question

Which of the following statements are incorrect?
(a) Deforestation increases temperature of the earth.
(b) Deforestation decreases chances of natural calamities.
(c) Deforestation decreases the ground water level.
(d) Soil erosion decreases desertification.
(e) Global warming causes droughts.

Answer 1

Deforestation will reduce the water holding capacity of the soil due to the lack of trees. This reduces the infiltration of water into the ground which increases the chances of flood. Soil erosion is actually a process of desertification. It usually involves the removal of nutrient-rich topsoil, leaving coarse, sandy particles with poor water-retaining ability.
