Which of the following explains how movement of material within earth causes volcanic eruptions
EleoNora [17]

The following choices are provided;

One plate moves below the other due to the movements in the inner core.

One plate moves below the other due to the movements in the mantle.

A plate slides past another due to the movements in the inner core.

A plate slides past another due to the movements in the mantle

The answer is; One plate moves below the other due to the movements in the mantle.

It is common that such convergent boundaries have a cascade of volcanic ranges. This is because as the oceanic plate moves below the continental plate the pressure and high temperatures cause the rock to melt and become magma. The magma makes it way up the crust through fissure and erupts.
