GENERAL KNOWLEDGE

Detailed explanation-1: -Geothermal energy is heat energy from the earth-Geo (earth) + thermal (heat). Geothermal resources are reservoirs of hot water that exist or are human made at varying temperatures and depths below the Earth’s surface.

Detailed explanation-2: -Geothermal energy is the heat produced deep in the Earth’s core. Geothermal energy is a clean, renewable resource that can be harnessed for use as heat and electricity. Geothermal energy is heat that is generated within the Earth. (Geo means “earth, ‘’ and thermal means “heat” in Greek.)

Detailed explanation-3: -In the case of “deep” geothermal energy, heat is extracted from geothermal reservoirs at depths greater than 400m which are accessed by drilling. “Hydrothermal energy” means that the energy contained below ground in warm/hot water is used; petrothermal energy uses the energy stored in the rock.

Detailed explanation-4: -Explanation: The process of producing energy by utilizing heat trapped inside the earth surface is called Geo thermal energy.

Detailed explanation-5: -The best-known natural displays of geothermal energy are volcanoes, fumaroles, boric-acid fumaroles and geysers.
