Metamorphic Rocks

Rocks that form when rocks that already exist are put under extreme amounts of heat and pressure.

• Igneous

• Metamorphic

• Sedimentary

NGSS.MS-ESS2-1

The type of metamorphism that occurs when plates collide and/or large amounts of magma rise up and apply extreme heat and pressure over a large area.

• regional metamorphism

• contact metamorphism

NGSS.HS-ESS1-5

The type of metamorphism that occurs when rock that already exists touches magma that intrudes it. The rock, instead of melting, gets baked.

• regional metamorphism

• contact metamorphism

The metamorphic rock texture that forms when pre-existing rock is put under extreme heat and pressure that is along one plane. This causes the mineral crystals to be flattened and compressed.

• foliated texture

• nonfoliated texture

The metamorphic rock texture that forms when pre-existing rock is put under extreme heat and pressure that is inward from every direction. This causes the mineral crystals to be larger and more defined.

• foliated texture

• nonfoliated texture
