- 1. The shape of the ground surface as determined by such major features as hills, mountains, or large plains.
- 4. The total stream discharge of water, including both surface and subsurface flow.
- 6. Pollution that occurs from a single source.
- 8. The changing of a liquid to a gas.
- 12. A stream of water bearing the waste of the land from higher to lower ground.
- 14. The amount of water, hail, sleet, snow, or other moisture received from clouds.
- 16. Flowing water from a natural or artificial channel.
- 17. A dense, compacted layer of soil under the surface that may interfere with the downward penetration of both roots and water.
- 18. The gaseous envelope surrounding the earth.
- 20. The amount of oxygen present in water in a dissolved state.
- 22. Living in water.
- 25. Pollution that is diffuse in both origin and in time and points of discharge, and depend heavily on weather conditions such as rainstorms and snowmelt. Pollutants can originate from natural source areas as well as areas affected by people’s activities.
- 27. The process of turning a vapor into a liquid.
- 28. The point where two streams meet.
- 31. In relation to water, changing from a solid to a liquid.
- 32. The pointed top of a mountain or ridge.
- 34. The seepage of water into soil or rock.
- 35. The passage of water through a plant from the roots through the vascular system to the atmosphere.

- 2. Water within the earth that supplies wells and springs.
- 3. Generating electricity by conversion of the energy of running water.
- 5. The ability or power to conduct or transmit electricity.
- 7. The most valuable natural resource and the most limiting factor in crop production.
- 9. An undesirable substance that is present, but is not intentionally added.
- 10. The downward movement of water through the soil in response to the pull of gravity.
- 11. Abbreviated TDS. It is a measure of the combined content of all inorganic and organic substances contained in a liquid in molecular or ionized suspended form.
- 13. The artificial application of water to soil for the purpose of increasing plant production.
- 15. One of the multitudinous features that taken together make up the surface of the earth. It includes all broad features, such as plain, plateau, and mountain, and also all the minor features, such as hill, valley, slope, canyon, and alluvial fan.
- 19. Any standing body of inland water.
- 21. An elongated, erosional depression usually occupied by a stream that has a downward slope conforming to the direction of flow of the occupying stream, and includes both bottomland and slopes.
- 23. Any broad or narrow, crested, elongated land feature that rises above or separates lowlands, plains, or valley basins.
- 24. Cloudiness of water caused by the presence of colloidal matter or other finely divided suspended matter.

- 29. Clearness of appearance.
- 30. Water on the surface, as lakes and rivers, in contrast to that underground.
- 33. In relation to water, changing from a liquid to a solid.
- 36. A geologic formation or structure that transmits water in a sufficient quantity to supply the needs for a water development.
