Potential regions for geothermal sites are which of the following?

1.Circum-Pacific belt

2.Himalayan region

3.Delta

4.Subduction zones

5.Rann of Kachchh

A1, 2 & 3 only

B2, 3 & 4 only

C1, 2 & 4 only ✓ Correct

D1, 4 & 5 only

Correct answer: (C) 1, 2 & 4 only

Explanation

Potential geothermal sites lie along the circum Pacific belt, the Himalayan region and subduction zones.

Statement 1 is right, as the circum Pacific belt is rich in volcanic and geothermal activity.

Statement 2 is right, as the Himalayan collision zone hosts many hot springs.

Statement 4 is right, as subduction zones bring heat close to the surface.

Statement 3 is wrong, since a delta is a sediment deposit with no special geothermal heat.

Statement 5 is wrong, as the Rann of Kachchh is a salt marsh, not a geothermal belt.
