Across
- 5. The top of the saturated zone, or depth to the groundwater under Earth's surface
- 6. A lake that stores water for human use
- 7. The continuous process by which water moves from Earth's surface to the atmosphere and back
- 8. The process by which molecules at the surface of a liquid absorb enough energy to change to the gaseous state
- 10. Water that fills the cracks and spaces in underground soil and rock layers
- 13. The land area that supplies water to a river system
- 15. A layer of permeable rock or soil in which the cracks and pores are totally filled with water
- 16. The state of water in which the molecules are moving at a medium speed and the substance takes on the shape of its container.
- 21. Discharge entering a stream at a specific, detectable point such as a pipe or outfall
- 22. A substance that dissolves another substance
- 23. The molecular attraction exerted between the surfaces of bodies in contact such as water molecules during capillary action
- 24. The act or state of sticking together tightly such as water molecules during surface tension
- 25. Water that falls to Earth as rain, snow, hail, or sleet
- 27. All the water found on the surface of the Earth in river systems, lakes, ponds, etc.
- 29. The change of state from a gas to a liquid
- 31. A land area that is covered with a shallow layer of water during some or all of the year.
Down
- 1. A smaller stream or river that feeds into a main river
- 2. The combined force of attraction among water molecules and with the molecules of surrounding material; caused by the adhesion of the water molecules to the surrounding material
- 3. Solid water; the state in which the water molecules are very close together and moving very slowly
- 4. The amount of heat needed to increase the temperature of a certain mass of substance by one degree Celsius
- 9. The tightness across the surface of water that is caused by the polar molecules pulling on one another; caused by the cohesion of the water molecules
- 11. A molecule that has electrically charged areas
- 12. Diffuse runoff from large areas of land; comes from a large land mass
- 14. The upward force exerted by a fluid on a submerged object
- 15. A mixture that forms when on substance is dissolved into another
- 17. Gaseous water; the state in which the water molecules are very far apart and moving very quickly and bumping into each other
- 18. A layer of rocks and soil above the water table in which the pores contain air as well as water
- 19. The change of state that occurs at zero degrees Celsius as the temperature lowers when liquid water turns into a solid
- 20. The change of state that occurs at zero degrees Celsius as the temperature rises when solid water turns into a liquid
- 26. The cloudiness or haziness of a fluid caused by individual particles (suspended solids) that are generally invisible to the naked eye, similar to smoke in air. The measurement of turbidity is a key test of water quality.
- 28. The land that water flows across or under on its way to a river; can include multiple watersheds
- 30. The mass per unit volume of an object
