Intro to Earth's Systemts

4. A landform with high elevation and high relief.
7. A line that forms the boundary between the land and the ocean or a lake.
9. The parts of Earth that contain living organisms.
10. A natural stream of water that flows into another body of water, such as an ocean, lake, or another river.
11. The portion of the hydrosphere that is frozen, including all the ice and snow on land, plus sea and lake ice.
14. The portion of Earth that consists of water in any of its forms, including oceans, glaciers, rivers, lakes, groundwater and water vapor.
18. The continual movement of water among Earth's atmosphere, oceans, and land surface through evaporation, condensation, and precipitation.
19. The change in state from a gas to a liquid.
20. The process by which water is lost through a plant's leaves.
21. A landform made of sediment that is deposited where a river flows into an ocean or lake.
22. The ability to do work or cause change.

1. An underground layer of rock or sediment that holds water.
2. A hole sunk into the ground to reach a supply of water.
3. The densest parts of Earth that include the crust, mantle, and core.
5. The shape of the land determined by elevation, relief, and landforms.
6. The relatively thin layer of gases that form Earth's outermost layer.
8. A process in which mapmakers determine distances and elevations using instruments and the principles of geometry.
12. Any form of water that falls from the clouds and reaches Earth's surface as rain, snow, sleet, or hail.
13. A hill of sand piled up by the wind.
15. The land area that supplies water to a river system.
16. The process by which molecules at the surface of a liquid absorb enough energy to change to a gas.
17. A feature on the surface of Earth, such as a coastline, dune, or mountain.
