C. atomic number is the answer
D)Heat within Earth
Explanation:
The heat from within the earth is as a result of plate tectonics. Plates on the earth are driven by heat within the earth through convection currents.
- Plate tectonics suggests that the earth are broken into slabs that moves on the weak and ductile material called asthenosphere.
- Heat from within the earth causes the melting of asthenosphere.
- The riding lithosphere which is cold will sink into the asthenoshpere.
- Hot mantle materials will move to the surface thereby setting up a convection current.
- Heat from within the earth rises to the surface due to plate movement.
