Across
  1. 3. The continuous movement of water between Earth’s surface and the atmosphere through evaporation, condensation, precipitation, and runoff.
  2. 5. The careful use and protection of natural resources like water to prevent waste or overuse.
  3. 14. The process where liquid water changes into water vapor (gas) due to heat from the sun.
  4. 15. Water that collects on the surface of Earth, such as in rivers, lakes, or oceans.
  5. 18. When water overflows onto land that is usually dry, often after heavy rain or rapid snowmelt.
  6. 22. The land area drained by a river and all its smaller streams and tributaries. (North Carolina has 17 major river basins.)
  7. 23. All the water on Earth, including oceans, rivers, lakes, groundwater, glaciers, and water vapor in the air.
  8. 24. Water found in oceans and seas that contains dissolved salts.
  9. 25. When water is removed from an aquifer faster than it can be replaced.
  10. 26. An area of land where all the water drains into the same river, lake, or ocean.
  11. 27. Water that fills the spaces and cracks in rocks and soil beneath Earth’s surface.
Down
  1. 1. Any form of water that falls from the atmosphere to Earth’s surface, such as rain, snow, sleet, or hail.
  2. 2. The process of water soaking down from the surface to refill an aquifer.
  3. 4. The process where water vapor cools and changes back into liquid droplets, forming clouds.
  4. 6. A layer of rock or sediment that holds and allows water to flow through it underground.
  5. 7. A scientist who studies water, its movement, and its effects on the environment.
  6. 8. Land areas that are saturated with water most of the time, like swamps, marshes, or bogs.
  7. 9. The process where water drops the sediment it was carrying, building up new landforms like deltas.
  8. 10. A measure of how clean or polluted water is, based on chemical, physical, and biological characteristics.
  9. 11. The amount of usable freshwater that is accessible for people, plants, and animals.
  10. 12. Water that flows over Earth’s surface, often into rivers, lakes, or oceans, instead of soaking into the ground.
  11. 13. The ways human activities (like pollution, farming, and construction) affect water systems.
  12. 14. The wearing away of soil and rock by moving water.
  13. 16. The release of water vapor from plant leaves into the atmosphere.
  14. 17. Rainwater or melted snow that flows over streets and land instead of soaking into the ground.
  15. 19. A coastal area where freshwater from rivers mixes with saltwater from the ocean.
  16. 20. The process of water soaking into the ground to become groundwater.
  17. 21. Water that contains little to no salt; found in rivers, lakes, and streams.
