2. water that flows over the ground surface rather than soaking into the ground
4. a large circular surface current pattern found in every ocean
7. subsidence- the gradual sinking of land
9. water - a mixture of salt and fresh water
10. basin- area of land drained by a river and its branches
13. a chemical intended to kill the insects and other organisms that damage crops
14. attraction between molecules of the same substance
17. has salt and fresh water
21. source origin- pollution that enters a body of water from a specific source
22. of saturation- zone where all open spaces in sediment and rock are completely filled with water
23. an area of land that drains all the streams and rainfall to a common outlet
24. the process by which surface water enters the soil
25. heat- the amount of energy required to raise the temperature. of 1 gram of a substance by 1 degree Celsius
26. source pollution- water pollution that does not have a specific point of origin

1. evaporation of water from the leaves of a plant
3. does not have any salt, and it can be rivers, lakes, streams, ponds, or wetlands
5. an area subject to flooding during a given number of years.
6. the amount of water in a stream that passes a certain point in a certain period of time
8. the volume of open spaces in rock or soil
11. excessive richness of nutrients in a lake or body of water, due to runoff, which causes a dense growth of plant life and death of animal life and a lack of oxygen
12. A body of rock or sediment that stores groundwater and allows the flow of groundwater
15. circulation- oceanic circulation driven by temperature differences in temperature and salinity
16. the ability of rock or soil to allow water to flow through it
18. table-upper level of the saturated zone of groundwater
19. uneven distribution of electrical chrage in a molecule
20. attraction between molecules of different substances
