| Term | Definition |
|---|---|
| Crust | The thin layer of rock that forms Earth's outer surface on land and in the ocean. |
| Mantle | The layer of very hot but mostly solid rock beneath Earth's crust. |
| Core | The layer of Earth below the mantle. |
| Tectonic Plate | One of the rigid layers of lithosphere. |
| Landfrom | A mountain, island, or continent formed by the collisions and separations of tectonic plates. |
| Deposition | The movement and accumulation or eroded soil. |
| Evaporation | A change in state from a liquid to a gas. |
| Transpiration | The release of vapor by plants through their leaves. |
| Precipitation | The return of water from the atmosphere to Earth's surface in the form of rain , snow, sleet, or hail, the process of separating a solid substance from a solution. |
| Condensation | A change in the state from a vapor to a liquid . |
| Aquifer | A spongelike formation of rock, sand, or gravel that holds water. |
| Crust | The thin layer of rock that forms Earth's outer surface on land in the ocean. |
| Mantle | The layer of very hot but mostly solid rock beneath Earth's crust. |

| Groundwater | Fresh water found below Earth's surface. |
| Law of conservation of matter | The principle that states that matter can change from but cannot be created or destroyed. |
| Nutrient | Matter that organisms need to carry out their life processes. |
| Biogeochemical cycle | The circulation of nutrients through the atmosphere; also called nutrient cycle. |
| Primary producers | An organism that can capture energy from the sun or from from chemicals and store it. |
| Photosynthesis | The process by which primary producers use sunlight to convert carbon dioxide and water into sugars, releasing oxygen. |
| Consumers | An organism that relies on other organisms for energy and nutrients . |
| Decomposer | An organism that breaks down nonliving matter into simple parts that can then be taken up and reused by primary producers. |
| Cellular respiration | The process by which organisms use oxygen to release the chemical energy of sugars, producing carbon dioxide and water. |
| Eutrophication | The introduction of phosphorus and nitrogen into a body of water that leads to an overgrowth of algae and other producers. |
| Nitrogen Fixation | The conversion of nitrogen gas into ammonia. |
