Across
  1. 2. broad, flat, fertile area extending out from a stream's bank that is covered with water during floods
  2. 4. triangular deposit, usually made up of silt and clay particles, that forms where a stream enters a large body of water
  3. 6. permeable underground layer through which groundwater flows relatively easily
  4. 9. 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 the streambed
  5. 10. depression in earth’s surface formed when a cave collapses or bedrock is dissolved by acidic rain or moist soil
  6. 11. water that flows downslope on Earth's surface and may enter a stream, river, or lake.
  7. 15. mound-shape dripstone deposit of calcium carbonate that forms on a cave's floor
  8. 16. upper boundary of the zone of saturation that rises during wet seasons and drops during dry periods
  9. 18. process by which lakes become rich in nutrients from the surrounding watershed, resulting in a change in the kind of organisms in the lake
  10. 19. 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 streambed
  11. 22. region above the water table where materials are moist, but pores contain mostly air
  12. 23. layer of impermeable material, such as silt, clay, or shale, that is a barrier to groundwater
  13. 24. process by which water from precipitation and runoff is added to the zone of saturation
Down
  1. 1. cone-shaped or cylindrical dripstone deposit of calcium carbonate that hangs like an icicle from the cave's ceiling
  2. 3. fountain of water that spurts above the land surface when a well taps a confined aquifer containing water under pressure
  3. 5. ability of a material to let water pass through, is high in material with large, well-connected pores and low in material with few pores or small pores
  4. 7. process during which a stream resumes downcutting toward its base level, increasing its rate of flow
  5. 8. difference between the water level in a pumped well and the original water table level
  6. 10. ground bordering each side of a stream that keeps the moving water confined
  7. 12. 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
  8. 13. land area drained by a stream system
  9. 14. explosive hot spring that erupts regularly
  10. 17. natural discharge of groundwater at earth's surface where an aquifer and an aquiclude come in contact
  11. 20. the elevation at which a stream enters another stream or body of water
  12. 21. elevated land that divides one watershed from another
