Question

What role does heat have in plate tectonics?

Question 4 options:

It thins out oceanic crust

It causes gas to escape the core of the earth

It causes volcanic eruptions

It moves crust plates around

Answer 1

the answer to your question is the option D, it moves crust plates around

Answer 2

Option (D)

Step-by-step explanation:

The heat plays the most important role that forms the convection current in the mantle.

According to the universally accepted plate tectonic theory, The earth's crust is comprised of numerous plates, both large and small. These plates are of 2 types, commonly termed as the continental and oceanic plate.

These plates are constantly in motion because of the formation of the convection current in the mantle. This current forms due to the heat supplied by the interior of the earth.

This heat allows the convection current to form in the mantle, forcing the plates to move over the less dense, viscous layer of asthenosphere.

Thus, the correct answer is option (D).
