Across
  1. 3. layer of impermeable material, such as silt, clay, or shale, that is a barrier to groundwater
  2. 4. region above the water table where materials are moist, but pores contain mostly air
  3. 10. region below Earth's surface where all the pores of a material are completely filled with groundwater
  4. 11. process by which precipitation that has fallen on land surfaces enters the ground and becomes groundwater
  5. 12. process by which water from precipitation and runoff is added to the zone of saturation
  6. 13. ability of a material to let water pass through
  7. 14. natural discharge of groundwater at Earth's surface where an aquifer and an aquiclude come in contact
Down
  1. 1. difference between the water level in a pumped well and the original water-table level
  2. 2. explosive hot spring that erupts regularly
  3. 5. fountain of water that spurts above the land surface when a well taps a deep, confined aquifer containing water under pressure
  4. 6. upper boundary of the zone of saturation that rises during wet seasons and drops during dry periods
  5. 7. deep hole drilled or dug into the ground to reach a reservoir of groundwater
  6. 8. permeable underground layer through which groundwater flows relatively easily
  7. 9. thermal spring with temperatures higher than that of the human body
