The process by which water, wind, ice and temperature break down rock
Rocks that have mineral grains arranged in bands or planes
Foliated metamorphic rock
Molten rock that is below the surface of the earth
Magma
The property that describes how the surface of a mineral reflects light
Luster
The process by which sediment is moved from one place to another.
Erosion
These are metamorphic rocks that do not have grains aligned in planes or bands.
Nonfoliated metamorphic rock
Molten rock that has made its way to the surface of the earth
Lava
Chemical Sedimentary Rock
A solid, geometric form that results from the repeating pattern of atoms or molecules
The sinking of regions of the crust to lower elevations. This creates a basin where sediments can be deposited.
Subsidence
The two processes that create metamorphic rocks
High temperature and pressure
Intrusive igneous rock
Rocks that form from the remains of once-living things.
Organic Sedimentary Rock
The scale that measures a mineral's resistance to being scratched.
The Mohs hardness scale
The process by which sediment comes to rest.
Deposition
A type of foliated metamorphic rock that has mineral grains arranged in a banded structure. Commonly used as flooring or roof tiles
Gneiss
Extrusive igneous rock
A type of limestone that has shell fragments cemented together.

Coquina
Not all minerals break along cleavage planes. Some ______________, or break unevenly.
Fracture
Common between tectonic plates, these are areas where a set of deep cracks form in earth's surface.
Rift zone
A nonfoliated metamorphic rock composed of calcite or dolomite. Usually used in building and statues
Marble
This is a specific type of Igneous rock that is sometimes called volcanic glass. 
Obsidian
A clastic sedimentary rock that is composed of differently sized rounded rocks that are cemented together

Conglomerate
Minerals that contain a combination of the two most common elements, silicon and oxygen
Silicate Minerals
