When sediments are dropped by water, wind, ice, or gravity, we call it _____________.
Deposition.
200
Underground cooling is generally slow. What is the result of the mineral crystals on these rocks?
Large mineral crystals
200
This type of sedimentary rock is formed from fragments of other land based rocks.
Clastic
200
Metamorphic processes take place how far below earth's surface?
Roughly 8 Kilometers
200
This type of metamorphism happens when magma touches layers of rock and the heat causes the rock layers to change.
Contact Metamorphism

Ripple marks in a sedimentary rock may indicate that the rock formed along a(n)__________ or ___________ bed.
Beach/stream bed
300
When talking about a lavas viscosity, the higher the viscosity it has, the __________ it moves.
Slower
300
Coal and fossiliferous limestone is what kind sedimentary rock?
Organic
300
A metamorphic rock can be classified according to its __________ and _________.
Texture and composition
300
The minerals in the rock are layered, which facilitates breakage along flat planes.
Foliation
300
What are sea shells made out of?
Calcium
400
Pumice has gas pockets because it formed so quickly. The lava solidified around the pockets of gas, creating holes in the rock. What descriptive word do we use to describe this?
Vesicular
400
Sandstones and siltstones form from smaller sediments that tend to create "layers"....what is the term we use to desribe this?
Stratification
400
Large-scale folding of rock during the process of mountain building is characteristic of a(n)__________________ metamorphism setting.
Regional metamorphism
400
Is a vertical "wall"of igneous rock that cuts across rock layers. (hint: Think of a dam)
Dike

The larger particles. This is called Horizontal Sorting.
500
This word describes alternating layers of different colored minerals in metamorphic rocks.
banding
