| Term | Definition |
|---|---|
| Crust | A thin layer of relatively cool rock that forms Earth's outer skin, both on dry land and in the ocean |
| Mantle | A layer of very hot but mostly solid rock below the crust |
| Core | Beneath the lower mantle is the very hot, very dense center of our planet. The ball-shaped core lies beneath the cool crust and the mostly solid mantle |
| Tectonic Plate | Tectonic plates (also called lithospheric plates) is a big, irregularly shaped slab of solid rock, generally composed of both continental and oceanic lithosphere |
| Landform | Features such as mountains (above and beneath the ocean's surface), islands, and continents |
| Deposition | The laying down of sediment carried by wind, flowing water, the sea or ice |
| Evaporation | The conversion of a substance from a liquid to a gas |
| Transpiration | The release of water vapor by plants through their leaves |
| Precipitation | Water returning to the Earth as a liquid E: Ice, snow, rain, etc |
| Condensation | A change in the state from a gas to a liquid |
| Aquifer | Layers of rock and soil that hold groundwater, fresh water found underground |
| Groundwater | The fresh water found underground |
| [LESSON 4 BEGINNING] - Law of Construction of Matter | Explains why the amount of matter in the environment stays the same as it flows through matter cycles, such as the water cycle |
| Nutrient | Matter that organisms require for their life processes |
| Biogeochemical cycle | Nutrients that cycle through all of Earth's sphere's and organisms |
| Primary Producer | Organisms, including plants and algae, that produce their own food |
| Photosynthesis | Producers pulling carbon dioxide out of their environment and combine it with water in the presence of sunlight. Chemical bonds in carbon dioxide (CO²), and water (H²O), are then broken, producing oxygen (O2) and carbohydrates such as glucose, (C6 H1 O6) |
| Consumer | Organisms, mainly animals, that eat other organisms to gain the nutrients they need |
| Decomposer | Organisms such as bacteria and fungi that break down wastes and dead organisms for nutrients |
| Cellular Respiration | The process in which organisms use oxygen to release the chemical energy of sugars and release CO2 and water. In gernal terms, it's the chemical reverse of photosynthesis |
| Eutrophication | The addition of phosphorus to bodies of water can lead to an overgrowth of producers (usually algae) |
| Nitrogen Fixation | The conversion of nitrogen gas into ammonia. This can occur by the intense energy of a lightning strike, or when air in the top layer of soil comes in contact with particular types of nitrogen-fixing bacteria. |
