Metamorphic rocks are rocks that change form under heat and pressure. They were once _ _ _ _ _ _ _ , _ _ _ _ _ _ _ _ _ _ _ or other metamorphic rocks.

Rock layers are a�ected by the _ _ _ _ _ of tectonic plate movement. These rock layers are under intense pressure. Pressure and friction produces _ _ _ _ that causes the chemical structure of the rock to change.

Heat can be produced by radioactive decay, the _ _ _ _ _ _ _ _ of tectonic plates and the pressure from overlying layers of rock. Heat can also come from magma deep under the ground.

Heated rock forms _ _ _ _ _ _ _ _. If it already contained crystals, these will get larger. Metamorphic changes will occur if rock is heated to 300 to 700 degrees Celsius. The rock becomes denser and the _ _ _ _ _ _ _ and chemical composition of the rock change. Sometimes these types of rocks can be cut and polished.
