A
solar radiation
B
seismic waves
C
radioactive decay
D
the greenhouse effect
Explanation: 

Detailed explanation-1: -Geothermal heat in deep-sea vents and on land provides energy for unique ecosystems with organisms that evolved to live in these areas. Heat inside the Earth from radioactive decay of elements and residual heat leftover from Earth’s formation. This heat drives plate tectonics and parts of the rock cycle.

Detailed explanation-2: -Decay heat is the heat released as a result of radioactive decay. This heat is produced as an effect of radiation on materials: the energy of the alpha, beta or gamma radiation is converted into the thermal movement of atoms.
