Science
| Definition | |
|---|---|
| Law of Conservation of Mass/Matter | matter can be neither created nor destroyed. |
| Law of Conservation of Energy | energy is neither created nor destroyed. |
| Evaporation | when a liquid turns into a gas. |
| Transpiration | the process in which water is lost as water vapor from the aerial parts of the plants through stomata. |
| Precipitation | When water falls back to the ground in the form of rain, sleet, snow, or hail. |
| Groundwater | water that exists underground in saturated zones beneath the land surface. |
| Runoff | anything that drains away, such as excess rainwater that is not absorbed by the earth. |
| Biotic Factor | living organisms that are part of an environment. |
| Abiotic Factor | a non-living part of an ecosystem that shapes its environment. |
| Biosphere | the part of Earth that can support life and includes all living things and the places they are found. |
| Producer | an organism that creates its own food or energy. |
| Consumer | an organism that cannot produce its own food and must eat other plants and/or animals to get energy. |
| Condensation | the process by which water vapor (water in its gas form) turns into liquid. |
| Water Cycle | the path that all water follows as it moves around Earth in different states. |
| Carbon Cycle | nature's way of reusing carbon atoms, which travel from the atmosphere into organisms in the Earth and then back into the atmosphere over and over again. |
| Nitrogen Cycle | made up of the processes that move nitrogen between the air, soil, animals, humans and plants. |
| Oxygen Cycle | the cycle whereby atmospheric oxygen is converted to carbon dioxide in animal respiration and regenerated by green plants in photosynthesis. |
| Deforestation | the clearing, or cutting down, of forests. |
| Cellular Respiration | the process by which organisms use oxygen to break down food molecules to get chemical energy for cell functions. |
| Photosynthesis | the process in which green plants use sunlight to make their own food. |
| Fossil Fuels | a natural substance formed from the buried remains of ancient organisms that can be used as a source of energy. |
| Nitrogen Fixation | the process by which atmospheric nitrogen is converted by either a natural or an industrial means to a form of nitrogen such as ammonia. |
| Ammonification | the step in the nitrogen cycle wherein death has occurred, and organic material is converted back into ammonium by decomposing organisms. |
| Interconnected | a principle that describes the intangible bond between different items. |
| Organism | a living thing that has an organized structure, can react to stimuli, reproduce, grow, adapt, and maintain homeostasis. |
| Denitrification | Extra nitrogen in the soil gets put back out into the air. |
