Across
- 3. triangular deposit, usually made up of silt and clay particles, that forms where a stream enters a large body of water
- 6. broad, flat, fertile area extending out from a stream's bank that is covered with water during floods
- 10. process by which precipitation that has fallen on land surfaces enters the ground and becomes groundwater
- 14. layer of impermeable material, such as silt, clay, or shale, that is a barrier to groundwater
- 15. the method of transport for all particles small enough to be held up by the turbulence of a stream's moving water
- 16. topography irregular topography with sinkholes, sinks, and sinking streams caused by groundwater dissolution of limestone.
- 17. curve or bend in a stream formed when a stream's slope decreases, water builds up in the stream channel, and moving water erodes away the sides of a streambed.
- 19. elevated land that divides one watershed from another
- 20. cone-shaped or cylindrical dripstone deposit of calcium carbonate that hangs like an icicle from a cave's ceiling
- 21. a natural underground opening connected to Earth's surface, usually formed when groundwater dissolves limestone.
- 22. measure of a volume of stream water that flows over a specific location in a particular amount of time
- 23. load describes sediments that are too heavy or large to be kept in suspension or solution and are pushed or rolled along the bottom of a strembed
- 25. of saturation region below Earth's surface where all the pores of a material are completely filled with goundwater
- 26. of aeration region above the water table where materials are moist, but pores contain mostly air
- 27. natural or human-made body of water that can form when a depression on land fills with water
- 29. table upper boundary of the zone of saturation that rises during wet seasons and drop during day periods
- 31. process by which a stream resumes downcutting toward its base level, increasing its rate of flow.
- 33. potentially devastating natural occurrence in which water spills over the sides of stream's banks onto adjacent land areas
- 34. permeable underground layer through which groundwater flows relatively easily
Down
- 1. level the elevation at which a stream enters another stream or body of water
- 2. mound-shaped dripstone deposit of calcium carbonate that forms on a cave's floor beneath a stalactite
- 4. explosive hot spring that erups regularly
- 5. process by which lakes become rich in nutrients from the surrounding watershed, resulting in a charge in the kinds of organisms in the lake.
- 7. difference between the water level in a pumped well and the original water-table level.
- 8. deep hole drilled or dug into the ground to reach a reservoir of groundwater
- 9. well fountain of water that spurts above the land surface when a well taps a confined aquifer containing water under pressure
- 11. channel narrow pathway carved into sediment or rock by the movement of surface water
- 12. ability of a material to let water pass through; is a high material with large, well-connected pores and low in material with few pores or small pores
- 13. bank ground bordering each side of a stream that keeps the moving water confined
- 15. natural discharge of groundwater at Earth's surface where an aquifer and an aquiclude come in contact
- 18. process by which water from precipitation and runoff is added to the zone of saturation
- 24. any land area, such as a bog or marsh, that is covered in water a large part of the year and supports specific plant species
- 28. depression in Earth's surface formed when a cave collapses or bedrock is dissolved by acidic rain or moist soil
- 29. land area drained by a stream system
- 30. water that flows downslope on Earth's surface and may enter a stream, or lake; its rate is influenced by the angle of slope, vegetation, rate of precipitation, and soil composition
- 32. spring thermal spring with temperatures higher than that of the human body
