Earth Science

1. A naturally formed underground chamber.
6. Levees- Earthen mounds built on the banks of a river.
7. Areas Typically Have...- Irregular terrain, with many depressions called sinkholes.
12. Load- The load contains dissolved materials such as sodium and calcium.
13. A hole bored into the zone of saturation.
15. An intermittent hot spring or fountain in which a column of water shoots up with great force at various intervals.
16. Dam- A barrier that controls the direction and flow of water.
18. the water that fills the cracks and spaces in underground soil and rock layers.
21. A wide and deep, loop-like bend in the course of a river.
22. The limestone that is formed from calcium carbonate left behind from the formation of caverns.
24. the quantity of water in a stream that passes a given point in a period of time.
25. The flat, low-lying portion of a stream valley subject to periodic flooding.
27. The sorted material deposited by a stream.
28. Water Cycle-the movement of water from the ground to the air and back to the ground by evaporation, condensation and precipitation.

2. Well- Any formation in which groundwater rises on its own under pressure.
3. in the Water Cycle- Annual average precipitation over Earth equals the amount of water that evaporates.
4. the emission of water vapor from the leaves of plants.
5. A depression produced in a region where groundwater has removed soluble rock.
8. A stream that flows into a larger stream or other body of water.
9. The imaginary line that separates drainage basins from one stream to another.
10. Spring- A natural spring of water at a temperature of 70 F or above.
11. Load- Sediment that is carried by a stream along the bottom of its channel.
14. A flow of groundwater formed by the water table intersecting the ground surface.
17. A measure that describes the maximum size of the particles a stream can carry.
19. Discharge increases.
20. Levees- Elevated ridges along a river's bank that are formed by the deposition of the river's sediment load.
23. The total amount of sediment a stream is able to transport.
26. Basin- The land area that contributes water to a stream.
