Across
- 2. Water on the surface, as lakes and rivers, in contrast to that underground.
- 8. The gaseous envelope surrounding the Earth.
- 11. The characteristic of a solid becoming a gas, or a gas becoming a solid without becoming a liquid, such as the conversion of snow to water vapor and the formation of frost.
- 12. The cycling movement of water through the stages of evaporation from oceans, to condensation into clouds, to the precipitation on Earth, and back to the oceans through rivers and streams.
- 15. Any standing body of inland water.
- 16. Living in water.
- 17. A stream of water-bearing the surface flow and ground flow from higher to lower ground.
- 19. The total stream discharge of water, including both surface and subsurface flow.
- 20. The movement of solid, liquid, and gaseous water through the atmosphere. Without this movement, the water evaporated over the ocean would not precipitate over land.
- 22. Wetland continuously or frequently covered by freshwater, tidal water, or standing saltwater. Marshes do not rely on rainfall for their water supply, and soft-stemmed plants are the dominant plant type.
- 23. Water falling to Earth from the atmosphere as rain, hail, sleet, snow, or other moisture received from clouds.
- 25. A measurement of the salt concentration in water; affects the survival of organisms living in aquatic environments.
- 28. The downward movement of water through the soil in response to the pull of gravity.
- 29. The changing of a liquid to a gas.
Down
- 1. Water within the Earth that supplies wells and spring.
- 3. The changing from a liquid to a solid.
- 4. The science and study of dealing with the properties, distribution, and circulation of water.
- 5. The addition of sediment, as by flowing water.
- 6. the process of turning a vapor into a liquid.
- 7. Water not high in salt content, with less than 0.2 percent salinity. This may not be the same as potable (drinking) water.
- 9. Flowing water form a natural or artificial channel.
- 10. Land area covered continuously or nearly continuously by standing water with trees or shrubs growing in the water. The water tends to be stagnant and usually dark and non-translucent.
- 13. An area bounded by geographic features in which precipitation is absorbed in the soil to form groundwater, which eventually emerges to become surface water and ultimately drains to a particular watercourse or body of water.
- 14. Water having more salinity than freshwater, but not as much as seawater.
- 18. Land area that is especially wet, usually with evergreens present, and covered with moss and peat; surface provides a spongy walk or sticky mud.
- 21. The passage of water through a plant from the roots through the vascular system to the atmosphere
- 24. The changing from a solid to a liquid.
- 26. Land areas that are flooded during all or part of the year.
- 27. Dihydrogen monoxide. The most valuable natural resource and the most limiting factor in crop production.
