UNIT 8 Vocabulary
Earth's Patterns of Change
| Question | Answer |
|---|---|
| Cementation | The process whereby dissolved minerals form crusts around sediments, binding them into rock. (tightly packed sediments) |
| Compaction | The process by which pressure compresses sediment together. (closely packed sediments) |
| Decomposition | The process in which dead organisms are broken down into simpler substances. |
| Fossil Fuel | Coal, oil, and natural gas formed when the remains of living organisms are subjected to intense heat and underground over millions of years. ( coal, oil, & natural gas) |
| Natural Gas | Colorless, odorless gas found deep underground; often found associated with oil deposits |
| Oil | Naturally occurring, thick, dark, liquid fossil fuel found beneath Earth's surface; can be refined into many different products such as gasoline, diesel, and asphalt. |
| Sedimentary Rock | Rocks that form from sediment that is deposited, compacted, and cemented together. ( sandstone, conglomerate, limestone, & shale) |
| Deposition | The laying down of sediments in a new location. (loosely packed sediments) |
| Erosion | The process of moving sediment from one location to another. |
| Landform | Naturally occurring features on Earth's surface that result from weathering, erosion, and deposition. |
| Weathering | The process of breaking down rock into smaller fragments without changing its composition - (two main types are: freeze-thaw & abrasion) |
