Key Idea 1: The Structure of the Earth and Plate Tectonics
Key Idea 3: Rock Classes and Minerals
Rocks can be divided into three main classes, depending on how they were formed.
Igneous rocks
- plutonic rocks are igneous rocks that are solidify underground
- volcanic rocks are igneous rocks that solidify on the surface

Metamorphic rocks from over time by high temperatures and a lot of pressure of pre-existing rocks which are deep down in the earth's crust
http://geology.com/rocks/metamorphic-rocks.shtml
Sedimentary rocks are formed by the depositing of sediment. This sediment is from different types of rocks that have been broken down into small fragments. Once deposited the layers of sediment become compacted, buried, and cemented together to form rock.

Minerals are naturally occurring crystalline chemical compounds that are found in the earth's crust. The crust is made up of 20 different minerals that are part of the rocks.

Silicates are the most abundant.
