Metamorphic Rocks Lesson - Fahad

They are formed when great heat and pressure are applied to rock, the rock can change both its shape and its composition

• Sedimentary Rocks

• Metamorphic Rocks

• Foliated Rocks

• Nonfoliated Rocks

Why are metamorphic rocks commonly found in mountains or near large masses of igneous rocks? Circle all that apply.

• The heat that can change a rock into metamorphic rock can come from pockets of magma.

• The wind that can change a rock into metamorphic rock can come from pockets of magma.

• Collision between earth’s plate causes great pressure  that deforms the rocks.
