GENERAL KNOWLEDGE

Detailed explanation-1: -As a result, deforestation will probably mean the soil will become increasingly fragile, leaving the area more vulnerable to natural disasters such as landslides and floods.

Detailed explanation-2: -It is a natural process. The major causes of soil erosion are namely, deforestation, overgrazing, forest fires and poor farming techniques. Hence the statement is correct.

Detailed explanation-3: -Soil erosion occurs primarily when dirt is left exposed to strong winds, hard rains, and flowing water. In some cases, human activities, especially farming and land clearing, leave soil vulnerable to erosion.

Detailed explanation-4: -Explanation: Deforestation removes the trees which hold the soil together by their roots. Removing the trees leaves the soil bare to wind and other elements which leads to desertification since the top soil is blown away, dried out or washed away by rain.
