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.

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.)
