Igneous Rock
Fossils are typically found within this type of rock.
Sedimentary rock
What type of rock can become metamorphic rock?
Any kind of rock
Conglomerate and limestone are what kind of rocks?
Sedimentary
This process is the initial layering of sand, silt, and/or clay.
Which type of igneous rock grows smaller crystals?

What kind of rock can become igneous rock?
Any type of rock
Pumice and granite are examples of this type of rock.
Igneous rocks
This term describes how layers in a sedimentary rock are usually visually distinguishable.
Stratification
This category of metamorphic rock has visible bands of minerals.
Foliated
What are the two processes that press and fuse sediments together into sedimentary rock?
Compaction and cementation
This type of sedimentary rock can be formed from layers of ancient dead plant material.
Coal
Identify the series of geologic processes that can transform a) magma into granite, then b) granite into sand, and then c) sand into sandstone.
a) cooling/crystallization
b) weathering and erosion
c) compacting and cementing
This type of metamorphic process changes a rock's composition when tectonic plates collide.
Regional Metamorphism
This type of metamorphic process changes a rock's composition when it touches molten rock.
Contact Metamorphism
What is the difference between weathering and erosion?
Weathering is the breaking down of rocks
Erosion is the transport of the sediment
