Question

1. what is geothermal energy?

heat generated from radioactive decay in earths core.
energy derived from the movement of tectonic plates.
energy derived from the sun.
energy derived from the moons gravitational pull.

Explanation:

Geothermal energy is heat from the Earth's interior. The main source of geothermal energy is the heat generated by radioactive decay in the Earth's core. Energy from tectonic plate movement is related to geothermal but not the primary definition. Energy from the Sun is solar energy, and from the Moon's pull is tidal energy. So the correct option is the first one.

Answer:

A. Heat generated from radioactive decay in Earth’s core.
