Which statement is correct about the flow of thermal energy inside Earth?

Question

1.Energy flow inside the crust causes magma to rise.
2.Energy flow inside the mantle causes magma to rise.
3.Energy flow inside the crust causes magma to sink deeper.
4.Energy flow inside the mantle causes magma to sink deeper.

Answer 1

The correct statement about the flow of thermal energy inside Earth is:

2. Energy flow inside the mantle causes magma to rise.

In the mantle, heat from the Earth's interior causes convection currents, which can lead to the rising of magma. As the hotter, less dense magma ascends, it can ultimately lead to volcanic activity on the surface.
