The heat energy from convection currents in magma also drives the rock cycle. Convection and movement of the plates causes rock to move between earths surface and interior. It provides heat that changes rocks inside Earths to form metamorphic rocks. Igneous rocks form when magma cools and solidifies. The older rocks that are broken down and converted to sedimentary rocks, might come from igneous and metamorphic rocks, or even older, sedimentary rocks. True or false without convection currents, there would be no rock cycle.

A: True
B: false
