Question

Soil erosion is caused due to:

• A. Strong winds
• B. Heavy rains
• C. Keeping the fields fallow for a long time
• D. All of the above
  

Answer 1

The correct option is D All of the above

Causes of soil erosion are:

(i) Uncovered loose soil gets eroded when it is exposed to strong winds. The winds carry away the soil particles to other places.

(ii) When rain falls on the unprotected topsoil, rainwater washes it down into the streams, rivers, etc.

(iii) Farmers loosen the topsoil of the agricultural fields either for cultivation or for removing the weeds. Sometimes due to certain reasons, these agricultural fields remain fallow (not cultivated) for a long time. Top loosened soil of these agricultural fields, thus, becomes prone to erosion by winds or rains.

So, the correct answer is option D.
