Geothermal field requires a combination of the following three conditions:
(A) A natural underground source of water
(B) A mountain in the vicinity
(C) An impermeable layer
(D) A coal mine in the vicinity
(E) A large mass of hot rock in the vicinity
Choose the most appropriate answer from the options given below:

Correct option is A

For a geothermal field to be viable, the following conditions are essential:
· (A) A natural underground source of water: This water is heated by the Earth's internal heat and used to generate steam or hot water for geothermal energy production.
· (C) An impermeable layer: This prevents the heated water from escaping and allows it to be trapped, maintaining pressure for efficient energy extraction.
· (E) A large mass of hot rock in the vicinity: The hot rock heats the water, making the geothermal system possible.
Information Booster:
The following are not necessary for a geothermal field:
· (B) A mountain in the vicinity: A mountain is not a requisite for geothermal activity.
· (D) A coal mine in the vicinity: Geothermal energy does not depend on coal mines or fossil fuel sources.
Additional Knowledge:
1. Geothermal energy: It harnesses heat from within the Earth to produce electricity or heating.
2. Natural underground water source: Crucial for steam or hot water generation in geothermal plants.
3. Impermeable layer: Essential to keep the heated water contained under pressure.
4. Hot rocks: These provide the necessary heat from the Earth’s interior, typically from volcanic or tectonic activity.
