Question:
In our country, large patches of forests are being cleared for cultivation of crops. The environmental impact of such a practice will lead to :
(a) soil erosion
(b) soil pollution
(c) soil conservation
(d) soil fertility
Solution:
(a) Soil erosion will be the environmental impact of clearing larger patches of forests (deforestation). When trees are cut down, then there are no
roots to bind the soil particles and prevent them from being carried away by strong wind or water.
This removal of top layer of soil is called soil erosion.
