Question

What are the two sources of heat in the earth's interior?

A.leftover heat from formation and radioactive decay

B.magma and liquid outer core

C.radioactive decay and convection currents

D.sunlight and meteor impacts

Answer 1

D. sunlight and meteor impacts I only think this because sunlight is our main source of heat and it's the only answer with sunlight in it

Answer 2

The two sources of heat in the Earth's interior are leftover heat from formation and radioactive decay (A).

Step-by-step explanation:

First, make sure to read the question carefully. The question is where the heat comes from in the Earth's interior. The heat from inside the Earth comes from leftover heat from formation and radiactive decay of isotopes in the mantle and the crust in equal amounts. This internal heat drives most geological processes and causes tectonic plates to move. In contrast sunlight is the most powerful source of heat on the surface.
