If a rock undergoes high heat and high pressure, what type of rock will it turn into?
Metamorphic
What are the two groups that sedimentary rocks fall under?
Foliated and non-foliated.
What are the two types of metamorphic rocks?
Foliated and non-foliated.
Explain the difference between intrusive and extrusive rocks.
Intrusive rocks are formed when lava cools on the earth surface. Extrusive rocks are form when magma cools under the earths surface.
Explain the reason of why magma or lava cools faster.
