Question

multiple choice 5 points
geothermal energy, a possible energy resource, is based on which phenomenon?
there are concentrations of heat in some places of the earths crust
heat energy from the sun penetrates deep into earth
human activity is the largest source of heat energy on earth
earths internal energy heats its surface more than the sun does

Explanation:

Geothermal energy relies on heat stored within the Earth. The correct phenomenon is that the Earth's internal energy (from radioactive decay and residual heat from formation) heats its surface in areas where this geothermal heat is more significant than solar heating, which is the basis for harnessing geothermal energy. The other options are incorrect: solar heat only penetrates the shallow Earth, human activity is not a major heat source, and concentrated crust heat is not the core basis of geothermal energy's definition.

Answer:

Earth's internal energy heats its surface more than the Sun does
