Metamorphic Rocks
Are metamorphic rocks created from weathering and erosion
No, they are formed from heat and pressure.
Is granite an igneous rock?
Yes
Are sedimentary rocks common?

Magma can become igneous rock through
Cooling
Are sedimentary rocks formed from heat and pressure?
No, they are formed in layers from weathering, erosion, deposition, compaction, and cementation.

What is the difference between foliated and nonfloated rocks?
Foliated metamorphic rocks contain parallel layers where as foliated rocks do not.

Which type of metamorphic rocks contain parallel layers?
Foliated
What are intrusive igneous rocks
Intrusive igneous rocks form underground. Lava cools slowly and creates large grains within the rock.
What is cementation and compaction
A process through which weight from the layers of sediment forces out fluids and decreases the space between grains
