| Term | Definition |
|---|---|
| Atmosphere | A mixture of gases that surrounds a planet or moon. |
| Hydrosphere | The portion of the earth that is water. |
| Biosphere | The part of earth where life exists includes all of the living organisms on earth |
| Cryosphere | Is the frozen water part of the Earth system. |
| Second law of thermodynamics | states that when energy transfer takes place matter becomes less organized with time. |
| Convection | The movement of matter due to differences in density that are caused by temperature variations can result in the transfer of energy as heat. |
| Closed System | A system in which both energy and matter are exchange with the surrounding |
| First law of thermodynamics | Is transferred between system but it cannot be created or destroyed |
| System | A set of particles or interacting components considered to be a distinct physical entity for the purpose of study . |
| Geosphere | The mostly solid,rocky part of the earth; extends from the center of the core to the surface of the crust |
| Matter | Anything that has mass and takes up space |
| Energy | Is a defined as the ability to do work |
| open system | A system in which energy, but no matt |
| Nitrogen cycle | the series of processes by which nitrogen and its compounds are interconverted in the environment and in living organisms, including nitrogen fixation and decomposition. |
| Nitrogen fixation | The process of changing free nitrogen gas into a usable form |
| Carbon Cycle | An essential substance in the fuels used for life processes. |
| Carbonate | forms from shells and bones of once-living organisms |
| Photosynthesis | Plants capture solar energy by a chemical process |
| Cellular Respiration | Process that releases energy by breaking down glucose and other food molecules in the presence of oxygen |
| Phosphorus cycle | Part of some molecules that organisms need to build cells. |
| Water cycle | The continuous movement of water between the atmosphere,the land,and the oceans. |
| Condensation | The change from a gas to a liquid |
| Precipitation | Any form of water that falls from clouds and reaches Earth's surface. |
| Evaporation | Liquid to gas |
| Ecology | The study of the complex relationship between living things and their nonliving or abiotic environment |
| Abiotic | Non- living |
| Biotic | Living |
| Ecosystem | A community of organisms and their abiotic environment |
| Producer | Organisms that make their own food |
| Consumer | Organisms that get their energy by eating producers |
| Decomposer | These consumers get energy by breaking down dead organisms |
| Carrying Capacity | The largest population that an environment can support at any given time. |
| Homeostasis | Cells and systems maintain a constant internal balance |
| Food Chain | The sequence in which organisms consume other organisms con be represented. |
| Food Web | A diagram that shows the feeding relationship among organisms in an ecosystem. |
| Energy Pyramid | A diagram that shows the amount of energy that moves from one feeding level to another in a food web |
| Uncertainty | doubt, the state of being unsure |
| Variation | Any difference between individuals of the same species. |
| Correlation | A measure of the extent to which two factors vary together, and thus of how well either factor predicts the other. |
| Causal | involving a cause |
| Erosion | Processes by which rock, sand, and soil are broken down and carried away (i.e. weathering, glaciation) |
| Coevolution | Process by which two species evolve in response to changes in each other |
| Viscosity | A liquid's resistance to flowing |
| Biogeology | Geographic distribution of species |
| Surface Tension | A measure of how difficult it is to stretch or break the surface of a liquid |
| Density | Mass / Volume |
| Polarity | A lack of electrical symmetry in a molecule. Charge differences on opposite ends of a structure. |
| Sublimation | Solid to gas |
| Vaporization | Liquid to gas |
| Specific Heat | The amount of energy required to raise the temperature of 1 gram of a substance by 1 degree celcius |
| Run Off | Water that flows over the ground surface rather than soaking into the ground. |
| Ground Water | underground water that is held in the soil and in pervious rocks |
| The total loss of water from an area, which equals the sum of the water lost by evaporation from the soil and other surfaces and the water lost by transpiration from organisms . |
