Question

Which best describes how geothermal energy is used to make electricity?

A.
Rocks are split to release energy that drives a steam turbine attached to an electrical generator.

B.
Heat energy from below the ground converts water to steam to drive a steam turbine attached to an electrical generator.

C.
Heat energy from below the ground drives liquid water though a turbine attached to an electrical generator.

D.
Heat energy from below ground heats and presuurizes air that drives a turbine attached to an electrical generator.

Answer 1

It's B, because rocks don't create energy (besides coal which isn't geothermal). And because the liquid comes up as steam (disproving C. and D.)
