SOIL EROSION AND CONSERVATION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The chief cause of accelerated erosion is:
A
Overfelling and overgrazing
B
Excessive rains
C
Wind storms
D
All of the above
Explanation: 

Detailed explanation-1: -Accelerated erosion occurs due to anthropogenic causes such as deforestation, slash-and-burn agriculture, intensive plowing, intensive and uncontrolled grazing, and biomass burning. These activities intensify the factors responsible for erosion and the erosion process is accelerated.

Detailed explanation-2: -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-3: -Abstract. Accelerated soil erosion occurs when anthropogenic processes modify soil, vegetation, or climatic conditions causing erosion rates at a location to exceed their natural variability. Identifying where and when accelerated erosion occurs is a critical first step toward its effective management.

Detailed explanation-4: -It occurs when people disturb the soil or the natural vegetation by cutting forests, overgrazing, ploughing hillsides, recreational activity (e.g., ATV vehicle uses), indiscriminate (arbitrary) burning, or construction of roads and buildings.
