Geothermal Energy
The word geothermal is an adjective. It means pertaining to heat energy extracted from the earth's interior.
Geothermal energy...heat.
of or relating to the heat in the interior of the earth
Geothermal gradient is the rate of increasing temperature with respect to an increasing depth in the Earth's interior. It is approximately 25 degrees Celsius per kilometer of depth.

Radioactivity decay should be responsible for the heat generated in the inner layers of the earth. Surely the gravity effect caused shear forces that could generate heat. Losing heat to the boundaries caused crystallization of the outer surface of eart, producing the crust. The crust acts as an heat isolating agent . But, actually, the decomposition of instable materials leading to, e.g. lead is followed by energy liberation and keeps the high temperature or, at least, compensates that fraction flowing to the universe.

Geothermal gradient is the increase of temperature in relation to the increasing depth in the Earth's interior. The Earth's internal heat source comes from the joined forces of residual heat from planetary accretion and heat produced through radioactive decay. It may also come from other sources.
It is called geothermal energy.
