| Question | Answer |
|---|---|
| crust | the outermost shell of a terrestrial planet |
| mantle | the mostly solid bulk of Earth's interior |
| core | the innermost layer of the Earth |
| tectonic plates | a massive, irregularly shaped slab of solid rock, generally composed of both continental and oceanic lithosphere |
| landforms | a natural feature of a land surface. |
| deposition | the laying down of sediment carried by wind, flowing water, the sea or ice |
| evaporation | Evaporation is a type of vaporization that occurs on the surface of a liquid as it changes into the gas phase. |
| traspiration | the process of water movement through a plant and its evaporation from aerial parts, such as leaves, stems and flowers |
| precipitation | any product of the condensation of atmospheric water vapor that falls from clouds due to gravitational pull. |
| condensation | Condensation is the process by which water vapor in the air is changed into liquid water |
| aquifiers | an underground layer of water-bearing material consisting of permeable or fractured rock, or of unconsolidated materials (gravel, sand, or silt) |
| groundwater | the water present beneath Earth's surface in rock and soil pore spaces and in the fractures of rock formations |
| law of conservation | The same amount of matter exists before and after the change—none is created or destroyed |
| nutrients | the movement and exchange of inorganic and organic matter back into the production of matter. |
| biogeochemical cycles | A biogeochemical cycle, or more generally a cycle of matter,[1] is the movement and transformation of chemical elements and compounds between living organisms, the atmosphere, and the Earth's crust. |
| primary producers | organisms that acquire their energy from sunlight and materials from nonliving sources |
| photosynthesis | A chemical process that occurs in plants, algae, and some types of bacteria, when they are exposed to sunlight. |
| consumers | organisms that need to eat to obtain energy. |
| decomposers | organisms that break down dead organisms and release the nutrients from the dead matter into the environment around them. |
| cellular respiration | the process by which cells derive energy from glucose. |
| eutrophication | sets off a chain reaction in the ecosystem, starting with an overabundance of algae and plants. |
| nitrogen fixation | Nitrogen fixation is a chemical process by which molecular dinitrogen (N 2) is converted into ammonia (NH 3) |
