Across
- 8. areas of rock and sediment with very small or nonexistant pore spaces and are therefore impermeable to water
- 11. liquid water enters soil and rocks which eventually becomes groundwater
- 13. going from a liquid to a gas
- 14. natural discharge of ground water
- 15. water taken up by plant roots
- 16. the amount of pore space
- 17. upper surface of the zone of saturation
- 18. rivers that flow into other streams
- 19. going from a gas to a liquid
- 20. liquid water leaving the atmosphere and falls to Earth
Down
- 1. the sinking of land caused by overuse of groundwater
- 2. dug or drilled below the water table
- 3. replenishing ground water levels through precipitation
- 4. all the land area whose water drains into a stream system
- 5. water flowing downslope along Earth's scludeurface
- 6. area above the water table which may contain some moisture but most spaces are filled with air
- 7. region in which groundwater completely fills all the pore spaces of a material
- 9. elevated land are that separates one watershed from another
- 10. evaporation from plants
- 12. areas of rock and sediment with relatively large pore spaces that are connected together
