What type of energy is derived from the heat of Earth’s interior?

Geothermal energy is the correct answer because it specifically refers to the heat that is generated and stored within the Earth. This energy originates from several sources, including the decay of radioactive isotopes, residual heat from the planet's formation, and heat from the Earth's core. Geothermal energy can be harnessed for various applications, such as electricity generation and direct heating.

The other types of energy mentioned do not derive from the Earth's interior. Solar energy comes from the sun, nuclear energy is produced through nuclear reactions typically in reactors, and tidal energy is generated from the gravitational forces exerted by the moon and sun on Earth's oceans. Each of these forms has its distinct sources and mechanisms for energy production, making geothermal energy unique in its foundation from the Earth's geological processes.
