This term refers to whether the grains are large,
small, or glassy:
What is texture?
row 1 column 1
1,2
Melted minerals cool at the surface to
form this type of rock.
What is EXTRUSIVE IGNEOUS ROCK
1,3
This is molten rock at the surface.
What is LAVA?
1,4
The reason this rock probably isn’t
considered igneous.(S.S.)
What is banding or layers?
2,1
This trait describes the way a rock reflects light.
What is luster?
2,2
A synonym for hardening due to cooling, also known as freezing.
What is SOLIDIFYING ?
2,3
This is a prefix used to mean outside of something.
What is EX ?
2,4
This rock was used by some for arrowheads
and spearheads.
What is OBSIDIAN?
3,1
This is a trait that we discussed in class thatigneous rocks never have.

3,2
This molten material begins the process
of forming an intrusive rock.
What is MAGMA?
3,3
These are the 2 types of igneous rock.
What are INTRUSIVE AND EXTRUSIVE ?
3,4
This could possibly have served as a flotation device for cavemen. (Probably not very
effective though. )
What is PUMICE ?
4,1
This trait means small or no crystals.
What is aphanitic?
4,2
This is the reason that some rocks do not form crystals at all.
What is COOL EXTREMELY QUICKLY ?
4,3
This means the chemicals or minerals in a rock.
What is COMPOSITION ?
4,4
Of the 2 general types of igneous rocks, these
form at a higher temperature.
What is INTRUSIVE?
5,1
This is the trait that rockshave because the crystalsare generally spread outin no particular pattern.
What is well mixed?
5,2
Some rocks have large crystals because they form
in this place.
What is BELOW THE SURFACE ?
5,3
This is when atoms form repeating patterns.
What is CRYSTAL?
5,4
These glimpses of the pastare generally not
found in igneous rocks because they can’t stand the heat needed to form
igneous rocks.
What are FOSSILS?
