| Chemical Sedimentary Rock | Sedimentary rocks that are created from the dissolved substances and they precipitate back into the soil. |
| Coarse-grained texture | Has crystals that are large and easy to see, most crystals are roughly the same size. These are usually formed underneath the Earth’s surface. |
| Contact Metamorphism | Results when rocks form near large plums of magma that increases the heat applied to each rock. |
| Crystallization | The process where magma cools and solidifies, either below or at a volcanic eruption at the surface. |
| Detrital Sedimentary Rocks | Sedimentary rocks that are formed for the weathering of different rocks and then reformed. |
| Disseminated Deposit | A deposit of metallic ions that are distributed in minute masses throughout an entire rock mass. |
| Evaporate Deposit | Formed from the evaporation of water leaving minerals that solidify into different minerals. |
| Extrusive (volcanic) | Igneous rocks that are formed because of a volcanic explosion. |
| Fine-grained Texture | Has crystals that cannot be seen with out the unaided eye usually cooled quickly. |
| Foliated Texture | Metamorphic rock that contains rock layers that are banded. |
| Glassy Texture | The result of very rapid cooling of magma. |
| Hydrothermal Solution | Created when hot, metal rich fluids containing metallic ions settle near the top of a magma chamber. |
| Igneous Rock | Result from the crystallization of magma beneath the earths surface or in volcanic eruptions. |
| Intrusive (plutonic) | Igneous rocks that are formed below the Earth’s surface and are can be seen as overlying layers are striped away. |
| Lava | Magma that has reached the surface and lost its gaseous components. |
| Lithification | Term meaning “conversion into rock.” |
| Magma | Molten material that forms inside Earth. |
| Metamorphic Rock | Rocks that created after being buried deep into the Earth’s surface and have intense heats and pressures applied. |
| Non-Foliated | Metamorphic rocks that contain all of one mineral and are essentially a single crystal. |
| Porphyritic Texture | Have some crystals which are much larger while other are much smaller and fine grain. |
| Regional Metamorphism | Usually the result of mountain building where there are high scale deformations and high heat applied. |
| Rock Cycle | Allow s us to view many of the interrelationships among different parts of the Earth’s system. |
| Sediment | The deposition of rock materials that are weathered in either ocean, swamps, floodplains, or rivers. |
| Sedimentary Rock | Created when sediment layers are compacted because of weight above and minerals fill in the pores spaces between with minerals. |
| Strata (beds) | Different layers of sediment that are laid down on top of one another. |
| Texture | Describes the overall appearance of an igneous rock, based on the size and arrangement of its interlocking crystals. |
| Vein Deposits | Where fluids of rocks move between small cracks and leave behind metallic ions. |
| Weathering | The day to day forces that decompose rocks into their constituent parts. |
