The figure shows part of what scientists think is happening in Earth’s mantle.

What process does the figure show occurring in the mantle?

Hot rock expands, becomes less dense, and rises toward the surface of Earth.

Hot rock expands, becomes more dense, and rises toward the surface of Earth.

Hot rock becomes less dense and moves towards the outer core.

Hot rock becomes more dense and moves towards the lithosphere.

Subduction occurs when one plate slides beneath another plate. The figure below shows the process of subduction. Notice that the oceanic plate slides beneath the continental plate.

What happens when the crustal plates move as shown in the figure?

An ocean forms.

Volcanic mountain ranges form.

Sea-floor spreading occurs as the oceanic plate moves.

A transform boundary forms where the subduction occurs.
