Seafloor spreading is

• the process where magma forms new ocean floor when two plates are pulled apart at a mid-ocean ridge

• the process of two plates colliding and pushing up to form mountains

• the process of magma heating, rising, cooling then sinking

Put these in the correct order

- magma cools

- magma heats

- magma rises

- magma sinks
