This rock is Foliated, fine grain size, and has a smooth dull surface
What is Slate
Where do most metamorphic rocks form between?
Metamorphic Rocks form under high temperature and pressure conditions (Deep within Earth's crust)
This metamorphic rock is known for its many visible bands, or foliations

This rock is medium–coarse grain size, compositional banding, and it's parents are shale, granite, and volcanic rocks
What is Gneiss
How many types of metamorphic rocks are there?
Two main types: Foliated and Non foliated
This term describes metamorphic rocks whose structures are not separated into bands
What is non foliated?
What are two types of metamorphic rocks?

This rock is nonfoliated, fizzes in HCI, and fused calcite grains
What is marble
What is contact setting, can't scratch glass plates, and it's parent rock is peridotite
