Rock Cycle
| Term | Definition |
|---|---|
| igneous rock | One of the three main rock types, formed from heating and cooling of magma/lava. |
| sedimentary rock | One of the three main rock types, made from pieces of other rocks. They are formed by the deposition and cementation of material at the Earth’s surface and within bodies of water. |
| metamorphic rock | One of the three main rock types. The rocks were once igneous or sedimentary and have changed from high temperatures and pressure. |
| weathering | The breaking down of rocks, soil, and minerals due to the weather. Freezing temperature, water, acid, or rain can affect landscapes. |
| erosion | Water, wind, or ice that moves sediments from one location and transports it to another. |
| deposition | Sediments or earth materials deposited in a new location. |
| Rock Cycle | A process where rocks change over time from igneous to sedimentary to metamorphic. Weathering, erosion, deposition, heat and pressure create those changes. |
| Magma | Mixture of molten or semi-molten rock that can be found underneath the surface of the earth. |
| crystallizing | Melting and crystallization occurs in the process of creating igneous rocks. A process where a solid forms where atoms are highly organized in a crystal. |
| basalt | An igneous rock formed from the cooling of lava or magma. |
| sediments | Material that comes from the weathering of rock and is carried and deposited by wind, water, or ice. |
| fossil fuels | A natural fuel (like coal or gas). They are the remains of organisms that lived a very long time ago. |
