Metamorphic Rocks

Metamorphic rocks form from...

• Cementing and Compaction of Sediments

• Melting of Magma

• Cooling of Magma

• Heat and Pressure

Metamorphic rocks that form strictly from intense pressure show mineral alignment. This texture is called...

• Foliated

• Nonfoliated

Gneiss is the most important metamorphic rock. What feature does gneiss show that is so important?

• It Shows Layers

• It Shows Banding

• It Shows Cleavage

• It Shows Fracture

Gneiss is the most intense metamorphism that can be observed. It is the greatest heat and pressure that can be placed on a rock. If gneiss is put under even higher heat, what will happen and what type of rock could it become?

• It Would Turn Into Sedimentary and It Would Melt

• It Would Turn Into Metamorphic and It Would Melt

• It Would Turn Into Igneous and It Would Melt
