Hydrology

8. The job of supervising or taking care of something. Like our water sources and our soil.
9. Excessive richness of nutrients in a lake or other body of water, frequently due to runoff from the land, which causes a dense growth of plant life and death of animal life from lack of oxygen.
11. The movement and filtering of a liquid through a medium.
12. The amount of dissolved calcium and magnesium in the water.
13. The process of solid particles suspended in a mixture separating from the medium and falling to the bottom of the container.
16. Water that is released from clouds in the sky; includes rain, snow, sleet, hail, and freezing rain.
19. The process in which matter changes from a liquid to a gas.
20. A salt or ester of nitric acid.
21. The uneven distribution of positive and negative charges across a molecule.
22. Living organisms such as plants, planktons, animals, and microbes, which are utilized to screen the health of the natural ecosystem in the environment.
24. The tendency of water to stick to other substances.

10. The process in plants by which water is taken up by the roots and released as water vapor through stomata in the leaves.
11. Property of a material that allows liquid or gas to pass through it.
14. Property of a material that prevents liquid or gas passing through it.
15. A measure of the average kinetic energy of the atoms in a system, used to express thermal energy in degrees.
17. The process in which water that is on the ground begins to be absorbed by the soil.
18. An overflow of fluid, as rainfall not absorbed by the soil.
23. A salt or ester of phosphoric acid.
