Metamorphic Rocks Lesson

The texture of a metamorphic rock gives indications as to the temperatures and pressure involved in metamorphism.

• True

• False

________________

is a foliated metamorphic rock with dark and light minerals.

• contact metamorphism

• foliated

• schist

• nonfoliated

• texture

___________________ metamorphic rocks have parallel layers of flat or elongated minerals.

• contact metamorphism

• foliated

• schist

• nonfoliated

• texture

metamorphism associated with mountain building

• contact metamorphism

• foliated rocks

• nonfoliated rocks

• plastic deformation

• regional metamorphism

permanent bending and folding of rocks

without melting

• contact metamorphism

• foliated rocks

• nonfoliated rocks

• plastic deformation

• regional metamorphism

happens when magma causes existing

rocks to change

• contact metamorphism

• foliated rocks

• nonfoliated rocks

• plastic deformation

• regional metamorphism

metamorphic rocks that contain parallel

layers of minerals

• contact metamorphism

• foliated rocks

• nonfoliated rocks

• plastic deformation

• regional metamorphism

metamorphic rocks that have interlocking mineral grains

• contact metamorphism

• foliated rocks

• nonfoliated rocks

• plastic deformation

• regional metamorphism

Pressure usually causes long minerals to align.

• True

• False

The existing rock that changes during metamorphism is the parent rock.

• True

• False
