100
The three categories all rocks can be put into.
What are igneous, sedimentary, and metamorphic?
100
This word means "resulting from or produced from fire."
What is Igneous?
200
Liquid rocks or minerals may be called _______

200
The movement of sediment.
What is erosion?
200
These two things are required for a metamorphic rock to form.
What are heat and pressure?
200
A rock that was sediment, then went under pressure, then was melted down and crystalized or cooled inside a volcano is this type of rock.

200
Means to change form?
What is metamorphism?
300
Two characteristics used to classify igneous rocks?
What is texture and composition?
300
When sediments are squeezed together
What is compaction?
300
the two settings of metamorphism
What is contact and regional metamorphism?
300
These types of rocks can become sediment by weathering.
What is sedimentary rock?
300
the resulting alignment usually gives the rock a layered or banded appearance.
What is foliated metamorphic rock?
400
Igneous rocks can be classified into these two types.
What are intrusive (basalt) and extrusive (granite) rocks?

400
Obsidian and pumice are igneous rocks with a ___________ texture
What is glassy?
400
rocks with very different size minerals experience different rates of cooling.
What is porphyritic texture?
500
This type of igneous rock are made when magma comes out of the Earth.
What is extrusive Basalt?
500
Some sedimentary rocks have ripple marks and mud cracks. These features are clues to this
What is the environment where the rock formed?
500
These are the two categories that metamorphic rocks can be put into.
What are foliated and nonfoliated?
500
