Vocabulary
| Term | Definition |
|---|---|
| Sediment | Small pieces of rock that are moved and deposited by water, wind, glaciers, and gravity. |
| Lithification | The physical and chemical processes that transform sediments into sedimentary rocks. |
| Cementation | Process of sedimentary rock formation that occurs when dissolved minerals precipitate out of groundwater and either a new mineral grows between the sediment grains or the same mineral grows between and over the grains. |
| Bedding | Horizontal layering in sedimentary rock that can range from a few millimeters to several meters thick. |
| Graded Bedding | Type of bedding in which particle sizes become progressively heavier and coarser toward the bottom layers. |
| Cross-bedding | Depositional feature of sedimentary rock that forms as inclined layers of sediment are carried forward across a horizontal surface. |
| Clastic Sedimentary Rock | Most common type of sedimentary rock, formed from the abundant deposits of loose sediments that accumulate on Earth's surface, classified according to the size of their particles. |
| Clastic | Rock and mineral fragments produced by weathering and erosion and classified according to particle size and shape. |
| Porosity | A measure of how much of a rock is open space. |
| Evaporite | A natural salt or mineral deposit left after the evaporation of a body of water. |
| Foliated | Consisting of thin sheets or laminae. |
| Nonfoliated | |
| Regional Metamorphism | Metamorphism affecting rocks over an extensive area as a result of the large-scale action of heat and pressure. |
| Contact Metamorphism | metamorphism due to contact with or proximity to an igneous intrusion. |
| Hydrothermal Metamorphism | |
| Rock Cycle | |
