What do we call the group of metamorphic rocks that have visible layers or bands of minerals within them?

• Sedimentary
• Stratified
• Foliated
• Unfoliated

What are the two main types of metamorphic rocks and how are they different?

• intrusive and extrusive; intrusive rocks are formed inside the earth and extrusive rocks are formed on the surface
• foliated and nonfoliated; foliated rocks do not have visible bands/layers and nonfoliated rocks do have visible bands/layers
• intrusive and extrusive; intrusive rocks are formed on the earth's surface and extrusive rocks are formed in the Earth
• foliated and nonfoliated; foliated rocks have visible bands/layers and nonfoliated rocks do not have visible bands/layers

__________  metamorphic rocks have mineral grains that are not arranged in distinct bands.

• Conglomerate
• Non-foliated
• Foliated
• Permeated

Which texture best describes the rock above?

• porphyritic 
• nonfoliated
• foliated
• clastic

Metamorphic Rocks are classified by

• Mineral Composition
• Texture (foliated / non foliated)
• Grain Sizes
• How they formed.
