Answer 1

Hint: Sand dunes refers to the hills of sand which are found near an ocean or desert. Shelter belts are a series of trees which are used to reduce soil erosion in arid areas.

Complete Answer: Looking at the above options:

Option A: Assam has no deserts. Therefore, sand dunes are not found there. This option is incorrect.

Option B: There are so serious problems related to sand dunes in Goa. This option is incorrect.

Option C: The shelter belts have played a major role in stabilizing sand dunes in the state of Rajasthan. This is because wind erosion is a very severe problem there , especially during the summer months when the dry and deserted soils are exposed to strong wind. In such cases, shelter belts have been found to be incredibly helpful in improving productivity of agricultural land in arid and semi-arid areas. This option is correct.

Option D: There is no major problem related to wind erosion in Karnataka. This option is incorrect.
