Question

choose the correct answer
what does \geothermal\ mean?
relating to heat from the earth
relating to the solar system

Explanation:

The word "geothermal" is derived from "geo" (meaning earth) and "thermal" (meaning related to heat). So it refers to heat from the earth. The option "relating to the solar system" is incorrect as that would relate to terms involving "solar" or celestial bodies in the solar system.

A. relating to heat from the earth
