yarga [219]

Answer:

D. hotter rock rises and cooler rock sinks.

Explanation:

We know that as we move towards Earth's center, the temperature rises. This rise in temperature causes rocks to melt (magma). The high temperature and melting of rocks decrease the density of material which makes it move upward. By moving upward, the molten rock starts turning solid and becomes denser again. Here, it sinks back due to gravity. This upward and downward movement of rocks due to density and temperature makes a convection cell.

PS: The formation of convection cells in Earth's interior is also the reason for plate tectonics.
