Metamorphic Rocks

____________________ metamorphic rocks have mineral grains with a random, interlocking texture.

• non foliated

• foliated

• regional

_________________ is a foliated metamorphic rock with dark and light minerals.

• quartzite

• schist

• gabbro

During _________________, the extreme temperature of magma changes the mineral composition of nearby rocks.

• regional metamorphism

• contact metamorphism

• plastic deformation

The degree of metamorphism is often determined by studying the ___________________ of a metamorphic rock.

• texture

• composition

• foliation

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

• nonfoliated

• foliated
