A dark-colored rock that has a lower silica content than granite.
What is basalt?
A rock that is changed by heat or pressure, or by chemical reactions.
What are metamorphic rocks?

What is luster?
Formed when water containing dissolved minerals seep into a rock.

What is a crystal?
Used to rank the hardness of minerals
What is the Mohs hardness scale?
What is a geode?
The 20 minerals make up most of the rocks of Earth's crust.
What are rock-forming minerals?
Igneous, sedimentary, and metamorphic rock.
Non-living things.
What is inorganic?
How a mineral splits easily along flat surfaces.
What is mineral cleavage?
The process by which atoms are arranged to material that has a crystal structure.
What is crystallization?
A light colored rock that has high silica content.
What is granite?
Rocks that form from the cooling of magma or lava.
What are igneous rocks?
How minerals split.
What is mineral cleavage and fracture?
How a mineral breaks apart in an irregular way.
What is fracture?
A mixture in which one substance is dissolved in another.
What is a solution?
What are grains?
