Question

Given below are three different phenomena. Which of them can result in soil erosion?
(1) Deforestation
(2) Crop rotation
(3) Overgrazing

• A. (1) and (2)
• B. (1) and (3)
• C. (3) and (2)
• D. (2) and (3)

Answer 1

The correct option is B (1) and (3)

$\bullet$ The removal of fertile topsoil by wind or water is called soil erosion.
$\bullet$ Deforestation or removal of trees along with overgrazing are two of the leading causes of soil erosion.
$\bullet$ Roots of plants penetrate deep into the soil, thereby preventing it from being washed/taken away by strong water flow/wind currents.
