Sedimentary : 

Sedimentary

How To Get The Sediment : 

How To Get The Sediment Weathering Deposition Erosion

Slide 4: 

Sedimentary rocks are made by the accumulation of particles of older rocks Three ways to be classified: clastic, chemical, and organic. Each way has a different way of forming sedimentary rocks.

Clastic : 

Clastic Lithification Compaction Cementation

Chemical : 

Chemical Not formed from sediments in the way that clastic sedimentary rocks are. formed from chemicals  dissolved in water

Organic : 

Organic

Metamorphic : 

Metamorphic Meta means change Morph means form Change form due to heat and pressure There are two types on Metamorphism: Contact metamorphism Regional metamorphism

Contact metamorphism : 

Contact metamorphism Magma forcing its way into existing rock low-grade metamorphism (low pressure) Makes nonfoliated rocks

Regional metamorphism : 

Regional metamorphism Plate Tectonics squeeze the rocks at the border force increases the pressure and causes heat from friction Make foliated rocks High grade

Igneous : 

Igneous Means fire These rocks are born from molten magma Formation starts in the mantle Only need extreme heat to form

Layers of the Earth : 

Layers of the Earth

Magma : 

Magma Uniform mixture of element These minerals make up the eight basic rock forming minerals for Igneous rocks

The eight minerals : 

The eight minerals

Slide 15: 

Two types of formation Extrusive – cools in about a week Intrusive – cools anywhere from 1000 to 1 million years
