Question

Desertification is due to

• A. Deforestation
• B. Soil-erosion caused by water
• C. Soil-erosion caused by wind
• D. Very high temperature and low rainfall

Answer 1

The correct option is A Deforestation

• Desertification is defined as a process of land degradation because of climatic variations and human activities.
• Overgrazing is the major cause of desertification worldwide.
• Other factors are urbanization, over-drafting of groundwater, and deforestation.
• Deforestation results in more soil erosion. Removal of the top layer of the soil exposes the lower, hard, and rocky layers. This soil has less humus and is less fertile.
• Gradually the fertile land gets converted into deserts. It is called desertification.

Thus the correct answer is option A.
