100
This is what igneous rock starts out as.
What is magma?
100
What are the small pieces of minerals and rock that are formed from weathering?
What is sediment?
100
This is what it takes for a rock to undergo metamorphism?
What is if the temperature and pressure of a rock is different than the environment in which the rock formed, then it will undergo metamorphism?
100

Rocks form in this position

What is horizontal? 

100

Boundary between the crust and mantle

What is the Moho? 

200
This is how igneous rock forms.
What is when magma cools and solidifies.
200

The step following compaction in the formation of sedimentary rocks

What is cementation? 

200
These are the two ways in which metamorphism can occur.
What are contact and regional metamorphism?
200

according to the law of superposition, these types of rocks are located on top of other rocks

What are newer/younger? 

200

The thinnest layer of the atmosphere

What is the crust (oceanic)? 

300
What are the two basic compositions of igneous rocks?
What are felsic and mafic.
300

Clastic rocks are named according to this

What is particle size? 

300
These are the two textures of metamorphic rock.
What is foliated and nonfoliated metamorphic rock?
300

Rocks shifting a long a crack

What is faulting?

300

The most common element in Earth's core

What is iron? 

400

Form when magma cools slowly

What are intrusive rocks?

400
This is the most noticeable feature of sedimentary rock.
What is that the sedimentary rocks are in layers or strata (single horizontal layer of rock)
400
This is texture of metamorphic rock in which the mineral grains are arranged in planes or bands.
What is foliated?
400
A large mass of igneous rock forced between or through layers of existing rock

What is an igneous intrusion? 

400

Scientists use these to determine the composition of earth's interior

What are seismic waves? 

500

form when magma cools quickly

What are extrusive rocks? 
500

These are the three main types of sedimentary rock.

What are clastic, chemical, and carbonate (organic)?

500
These minerals are used to estimate the temperature, depth, and pressure at which a rock undergoes metamorphism. Many of these minerals only form in metamorphic rock.
What are index minerals?
500

the bending of rock from pressure

What is folding? 

500

Put these in order from the center outward
