Potential regions of geothermal sites are: A. Circum pacific belt B. Himalayan Region C. Delta D. Subduction zones E. Rann of Kachchh Choose the correct answer from the options given below:
A, B and D only
Geothermal energy is tapped where the Earth's internal heat comes close to the surface — chiefly along plate boundaries and zones of active volcanism or tectonic movement.
The Circum-Pacific belt (the "Ring of Fire") is dotted with volcanoes and geothermal fields, so it is a prime geothermal region. The Himalayan region hosts many hot springs, such as the Puga valley in Ladakh, marking real geothermal potential. Subduction zones — where one plate plunges beneath another, generating heat and volcanism — are classic geothermal provinces. Hence A, B and D are correct.
A delta is a low-energy landform built up by river sediment near the sea; it has no internal heat source, so it is not a geothermal site. The Rann of Kachchh is a seasonal salt marsh, not a tectonically hot zone. Therefore C and E are wrong.
This leaves the Circum-Pacific belt, the Himalayan region and subduction zones as the potential geothermal sites.
Takeaway: geothermal potential follows tectonically and volcanically active belts, not deltas or salt flats.
Correct answer: A, B and D only.
