Three types of sedimentary rocks

Clastic, Chemical, Organic

4 step process of sedimentary rock formation

weathering, transportation, deposition, lithification

Clastic

Most common type of rock, made from pieces of other rocks - Conglomerate, Breccia, Sandstone, and Shale

Chemical

Derived from chemicals naturally precipitated from lakes and seas (evaporation) - Limestone and dolostone

Biological/Organic

have accumulations of organic remains like marine organisms that died, settled to the sea floor, and were buried and cemented together.

Clastic rocks in order of the energy from the environment where they formed. (high to low)

Conglomerate, Breccia, Sandstone, Shale
