The Rock Cycle Processes Transition and Chart » Geology

Igneous Rock Cycle Process When rocks are pushed deep under the surface they can melt into magma If the conditions for the magma to remain liquid are no longer present they are cooled and incorporated into an igneous rock A rock that cools in the earth is called intrusive or plutonic and it cools very slowly to produce a coarse-grained...
