उत्तर
Desertification is the washing away of the earth’s top soil due to various human activities.
Explanation:
Desertification is a form of land degradation mainly caused by agricultural practices, deforestation, bad water management, over-cultivation, and overgrazing. These activities remove the vegetation cover and exhaust the soil nutrients, leading to the loss of the fertile top soil, which is essential for crop production.
