Earth Systems
Earth System Interactions, Water Distribution, and Human Impact
| Question | Answer |
|---|---|
| the solid part of Earth. It includes the crust, the mantle, and the core. The crust is the outermost layer, and the core is the innermost layer | Geosphere |
| the combined mass of water found on, above, and below the surface of the Earth. The hydrosphere includes water in the atmosphere, on the surface of the Earth, and underground | Hydrosphere |
| the part of Earth where life can be found, including all living things like plants, animals, and tiny bacteria, from the highest mountaintops to the deepest ocean trenches | Biosphere |
| the layers of gases surrounding a planet or other celestial body composed of abo;ut 78% nitrogen, 21% oxygen | Atmosphere |
| the continuous process of water moving between the Earth's atmosphere, land, and oceans | Water Cycle |
| heat causes water to change from a liquid into a gas and rise into the atmosphere | Evaporation |
| water vapor cools and turns back into a liquid; forming clouds, dew, fog, etc. | Condensation |
| the water that falls back to Earth as rain, snow, or hail | Precipitation |
| the process by which water evaporates from plants' leaves into the atmosphere | Transpiration |
| how water is spread out across the Earth; like in oceans, lakes, rivers, glaciers, and even underground. Most water is in the oceans as saltwater and only a small amount is fresh water available for drinking and use by people and animals. | Water Distribution |
| a place where a large amount of water is stored on Earth | Reservoir |
| the action or influence of people, groups, or things on one another | Interaction |
| a supply of something that is useful | Resource |
| a group of parts that work together | System |
| water in the form of a gas | Water Vapor |
| water that contains very little or no salt; primarily found in sources like rivers, lakes, glaciers, and underground reservoirs | Freshwater |
| the changes people make to the environment around them, like cutting down trees, polluting the air and water, or using too much energy, which can affect plants, animals, and the planet as a whole | Human Impact |
| the increase in the number of humans on Earth; which can affect the resources available for survival | Population Growth |
| the relationship between people and the environment, and the actions people take to protect the natural world. It involves using natural resources wisely and protecting the environment | Conservation |
| how much fresh water is accessible for people to use, like for drinking, growing crops, and cleaning, in a certain area | Water Availabilty |
