| Term | Definition |
|---|---|
| Crust | The thin layer of rock that forms Earth's outer surface |
| 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 the lithosphere |
| Landform | A mountain, island, or continent formed by collision and separations of tectonic plates |
| Deposition | The movement and accumulation of eroded soil |
| Evaporation | A change in the state from a liquid to a gas |
| Transpiration | The release of water 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 |
| Condensation | A change in the state from a vapor to a liquid |
| Aquifer | A sponge-like formation of rock, sand, or gravel that holds water |
| Groundwater | Fresh water found below the Earth's surface |
| Law of Conservation of Matter | The principle that states that matter can change but cannot be created or destroyed |
| Nutrient | Matter that organisms need to carry out their life processes |
| Biogeochemical cycle | The circulation of nutrients throughout the atmosphere; also called the nutrients cycle |
| Primary Producer | An organism that can capture energy from the sun or from chemicals and store it; also called autotroph |
| Photosynthesis | The process by which primary producers use sunlight to convert carbon dioxide and water into sugar, releasing oxygen |
| Consumer | An organism that relies on other organisms for energy and nutrients; also called heterotroph |
| Decomposer | An organism (e.g., a fungus or bacterium) that breaks down nonliving matter into simple parts that can be taken up and reused by primary producers |
| Cellular Respiration | The process by which an organism uses oxygen to release the chemical energies 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 conversation of nitrogen gas into ammonia |
