Small particles of material that come from rocks or living things. These are used to make sedimentary rock.
Sediments
Two things needed to create metamorphic rock.
What is heat and pressure?
Newest rocks layers will always be at the _____ in undisturbed horizontal sedimentary rock layers.
What is the top?
Melted rock that reaches the surface of the Earth is called_____.
Lava
The break up of rocks caused by freezing and thawing, plat roots, acid, or other forces on the rock.
What is weathering?
Liquid rock found below the Earth's surface.
What is magma?
The oldest rock layers will tend to be at the ________ of horizontal, undisturbed, sedimentary rock layers.
What is the bottom?
Type of rock usually found above subduction zones or volcanoes.
Igneous
Process where material becomes deposited at the bottom of a body of water.
Deposition
Rock type(s) that can become metamorphic
Sedimentary or Igneous
This law states that in undisturbed rock layers, the oldest layers are at the bottom and the youngest ones are at the top.
What is the Law of Superposition?
What are two processes that can cause erosion?
Answers may vary, but may include water, wind, gravity, ice, animals, etc.
What is erosion
Movement of particles or sediments due to water, wind, gravity, etc.

B and A
Sedimentary
Means "of or from fire"
Igneous
This type of rock is usually foliated (contains layers)
Metamorphic Rock
Method used to determine the absolute age of a rock.
Radioactive dating
Rock formed through deposition and cementation
