| Bioclastic Sedimentary Rock Examples | Coal, Chalk. |
| Define: Stream Capacity | The volume of sediment a stream is capable of carrying. |
| Define: Stream Competence | The size of clast a stream is capable of carrying. |
| Define: Relief | The difference between High and Low elevations. |
| Explain how Evaporites are formed | Amount of evaporation is greater than added water, leaving minerals behind, which become rocks. |
| Define: Eustacy | Changes in sea level. |
| Define: Saturation | Full of particular mineral in dissolved state |
| Explain how Limestone is formed | Forms in warm, shallow marine environments |
| Principle ingredient of Limestone | CaCO3 - Calcium Carbonate |
| Explain how coal is formed | Formed in Anoxic environments with no decay. Vegetation accumulates in thickness, becomes peat, then becomes coal. |
