Across
- 2. A mass of glacial land ice extending more than 50 000 km².
- 3. akin to a "sponge" that holds groundwater in tiny cracks, cavities and pores between mineral grains.
- 4. A permanent body of ice, which consists of largely of recrystallized snow.
- 6. A moving body of surface water that flows downslope towards sea level because of gravity.
- 7. saltiness of water
- 12. propelled by sinking of cold, salty, and dense water in the polar regions,and rising of the warm, less salty water of the Tropics.
- 14. natural event wherein an area that is usually dry is submerged under water.
- 15. cycle the movement of water around Earth's surface and its subsystem.
- 16. Are barriers constructed along streams to contain the flow of water.
- 17. the boundary between the zone of aeration and the zone of saturation.
- 18. gradual sinking of land
- 19. part of Earth's subsystem containing the oceans,lakes,streams,underground water,snow and ice.
Down
- 1. involves the reduction of the mineral content by taking salt out of seawater and brackish water to produce freshwater.
- 3. mining of certain metals causing surface water to become acidic producing a discharge.
- 5. large inland bodies of fresh water or saline water.
- 8. the average length of time spent by water molecule in a reservoir
- 9. A fresh water found in the rock and soil layers beneath the surface.
- 10. land areas where water covers the surface for significant periods.
- 11. consists of relatively warm, low-density water, home of marine plants and animals.
- 13. A soil, rock, or sediments that is frozen for more than 2 consecutive years.
