Sedimentary rocks are formed from sediments and pressed together in these
What are layers?
100
Metamorphic rocks are formed by these processes
What is heat and pressure
100
Melted rock below the earth's surface
What is magma?

Define erosion
Erosion happens when rocks and sediments are picked up and moved to another place
100
There are this many levels on the Mohs Hardness Scale
10

Sedimentary Rock goes through this process to become a metamoprhic rock
What is Heat and Pressure?
200
A metamorphic rock goes through this process to become sedimentary
What is weathering?
200
A crumbly, lightweight rock with tiny holes
What is pumice?
200
This will happen to a crack in a rock on freezing day
(must explain why)
The crack will get bigger because water that goes into the crack will expand when frozen and push the side of the crack, widening it.

The 5 properties used to identify minerals
What are color, Streak, Cleavage, Luster, and Magnetism
300
True or False Sedimentary rocks are easily changed by wind and water
True
300
Force that squeezes rocks together
What is pressure
300
Igneous rocks are rocks that are formed when _________ and _________
What is cooled and hardened?
300
This is the difference between physical and chemical weathering
Physical weathering only changes the size and shape of a rock or mineral. Chemical weathering changes the substance entirely.
300
True or False: The streak color of Fluorite is pale green.
False
400
This rock is usually white and formed on the bottom of oceans from the remains of once-living things
What is limestone?
400
Marble's original type of rock
What is limestone?
400
This determines the size of mineral crystals in an igneous rock.
What is the speed at which it cools down?
Cools slowly = larger crystals
Cools quickly = smaller crystals

Describe how a canyon is formed
The most familiar type of canyon is probably the river canyon. The water pressure of a river can cut deep into a river bed. Sediments from the river bed are carried downstream, creating a deep, narrow channel.

Fill in the blank: ________ fizzes in __________.
Calcite fizzes in vinegar.

These are the 2 processes by which sediment is squeezes and glued together into a new rock
What is compaction and cementation?
500
True or False Metamorphic rocks are formed from only sedimentary and igneous rocks
What is FALSE (They can also be formed from other metamorphic rocks. Physical and mineral make-up change)
500
All rocks can become igneous rocks through this
What is melting?
