Erosion

What materials are igneous rock made of?
Lava and magma
100
What are the 2 causes of metamorphism?
Heat and pressure

Define the vocabulary term "rock cycle"
The process by which rocks are formed from one another.

Describe how intrusive rock feels compared to extrusive rock.
Intrusive feels rough and bumpy. Extrusive feels smooth.
200
What are the 2 types of sedimentary rock?
Clastic and Chemical
200
What are two kinds of igneous rock?
Intrusive and Extrusive
200
Why are metamorphic rocks uncommon on the Earth's crust?
They form deep in the Earth's crust and require a volcano or excessive weathering to push them up.

Understanding the Rock Cycle help us...
a. Learn how we can recycle rocks, so we don’t run out
b. Understand how rocks are used as building materials
c. Learn how to make jewelry from rocks
d. Understand how rocks change from one kind to another
d. Understand how rocks change from one kind to another.

How do farmers depend on sedimentary rock?
Farmers use limestone to make lime for treating acidic soil and phosphate to make fertilizer.
300
Why are Sedimentary rocks often called secondary rocks?
Sedimentary rocks are made from already-formed rocks.
300
What are large plutons that are exposed at the Earth's surface by erosion called?
batholiths
300
What are the 2 types of metamorphic rock?
Foliated and nonfoliated
300
Describe how igneous rock turns into metamorphic rock.
Heat and pressure (Not all of the way melted)
300
What kind of rocks are pumice, granite, and obsidian?
Igneous
400
Explain how chemical rocks are formed.
Chemical rocks are formed from minerals that were dissolved in water, came out of solution, and were then deposited.
400
Describe how the crystals in intrusive and extrusive rocks differ and explain why they do.
Intrusive rocks cool slowly and have large crystals. Extrusive rocks cool faster and have little or no crystals.
400
What 2 metamorphic rocks did we study that are popular as building materials?
Slate and Marble
400
Describe how metamorphic rock can become igneous rock.
Metamorphic rock gets pushed deep into the Earth by a volcano/earthquake and heat and pressure melt it. Contact or regional metamorphism.

Describe the order in which fine, medium, and coarse particles settle as swift-moving water slows down.
Coarse, medium, fine; the large the particle, the stronger the force needed to carry it. As water slows, large particles settle first.

Name the 6 processes involved in making a sedimentary rock. *They must be in order.*
In a newspaper article, a man claims to have a valuable fossil in a chunk of granite. What is wrong with this claim?
Granite is formed underground by cooled magma underground. For it to have a fossil in it, the organism would have to be able to live in melted rock deep in the Earth.
500
Name the 2 kinds of metamorphism and tell how they are different from each other.
Regional-when plates carrying land masses collide and rocks crumple and fold.
Contact-magma rises through Earth's crust and touches "bakes" existing rock.
