Across
- 4. – The changing from a solid to a liquid.
- 6. – A stream of water-bearing the surface flow and ground flow from higher to lower ground.
- 8. – Any standing body of inland water.
- 9. – 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 all the minor features, such as hill, valley, slope, canyon, and alluvial fan.
- 12. – Living in water.
- 15. – Water within the Earth that supplies wells and springs.
- 17. – 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.
- 19. – 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.
- 20. – Dihydrogen monoxide. The most valuable natural resource and the most limiting factor in crop production.
- 21. – The passage of water through a plant from the roots through the vascular system to the atmosphere.
- 22. – The science and study of dealing with the properties, distribution, and circulation of water.
- 24. – A measurement of the salt concentration in water; affects the survival of organisms living in aquatic environments.
- 26. – The process of turning a vapor into a liquid.
- 27. – The changing from a liquid to a solid
- 28. – 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.
- 29. – Water having more salinity than freshwater, but not as much as seawater.
Down
- 1. – Land area that is especially wet, usually with evergreens present, and covered with moss and peat; surface provides a spongy walk or sticky mud.
- 2. – Water on the surface, as lakes and rivers, in contrast to that underground.
- 3. – Flowing water from a natural or artificial channel.
- 5. – The changing of a liquid to a gas.
- 7. – 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.
- 10. – 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.
- 11. – The total stream discharge of water, including both surface and subsurface flow.
- 13. – Water falling to Earth from the atmosphere as rain, hail, sleet, snow, or other moisture received from clouds.
- 14. – The gaseous envelope surrounding the Earth.
- 16. – Water that is not high in salt content, with less than 0.2 percent salinity. This may not be the same as potable (drinking) water.
- 18. – The addition of sediment, as by flowing water.
- 19. – 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.
- 23. – Land areas that are flooded during all or part of the year.
- 25. – The downward movement of water through the soil in response to the pull of gravity.
