This type of rock is formed from sand and other materials being deposited over time cemented in a solid
What is sedimentary rock
100
As material is exposed to high temperatures and pressures, the minerals change to form new minerals in this new type of rock
What is metamorphic rock?
100
Hot magma cools into this type of solid rock.
What is igneous rock?
100
Evidence that shows the earths crust is rising in an area.
What is uplift?

What is Animals in the fossil record are ancestors of animals that exist today.
200
The term that describes what happens to loose sediment when it is formed into a sedimentary rock.
What is deposition?

In the rock cycle lab using pieces of crayon, what two things did pushing down on your tin foil while on the hot plate simulate?
What is increased heat and pressure?
200
A type of igneous rock that cools on the earths surface.
What is extrusive igneous rock?
200
There are two destructive processes in the rock cycle, name them.
What are weathering and erosion?
200
The law the states that a rock unit that cuts through another rock unit is always younger
What is law of crosscutting relationship?
300
Sedimentary rock is easily broken down by these two destructive processes.
What is weathering and erosion?
300
A rock which stays close to the earths surface cannot become a metamorphic rock because a lack of these two things.
What is a lack of heat and pressure
300
This change of state occurs when magma turns into an igneous rock.
What is from a liquid to a solid?
300
There are a few constructive processes in the forming of new rock, name one.
What are deposition, lava cooling to form new rock, and pressure to form new rock?
300
This type of fossil existed for only a short period of time.
What is an index fossil?
400
These are found in sedimentary rock and show us what kind of organsims lived in the past
What are fossils?
400
The types of rock that can become metamorphic with heat and pressure.
What are igneous or sedimentary rock?
400
Magma cooling under the earths surface in cracks or chambers would be considered this type of igneous rock
What is Intrusive Igneous rock?
400
Placing rock layers in order from youngest to oldest.
What is relative dating?

What is by sand and other materials being deposited and hardened over time?
500
Shale is a sedimentary rock that can be turned into a metaporphic rock called slate. What is needed to make this transition.
What is heat and pressure?

Which part of the rock cycle helps form igneous rock, but not other types of rock: Erosion, Melting, Deposition, or Metaporphism.
What is melting?
500
Describe the law of superposition.
What is younger layers are found on top of older layers in undisturbed earth?
500
This is the best reason no dinosaur fossils have been found in Minnesota.
What is the fossils were in rock layers that were eroded away?
