Metamorphic Rock

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
