Across
- 1. the continuous movement of water from reservoir to reservoir
- 4. when particles move slowly/vibrate and are tightly packed
- 5. when a liquid becomes a gas
- 8. height above or below a given location
- 9. when particles move at a medium speed and slide past each other
- 10. when water falls to the ground as rain, snow, sleet, hail...
- 11. forms that matter can take on, including solid, liquid, and gas
- 12. the driving force behind evaporation, condensation, melting, and freezing
- 15. the tiny invisible pieces that matter is made of
- 17. the driving for behind precipitation, runoff, and infiltration
- 18. a series of reservoirs that are connected through the movement of water
- 19. then a liquid becomes a gas through a plant
Down
- 2. when a gas becomes a liquid
- 3. the natural and human-made places where water is found
- 4. water located on the surface of the earth such as lakes and streams
- 6. when water seeps into the ground or soil
- 7. when water flows along the surface of the ground
- 13. when a solid becomes a liquid
- 14. when a liquid becomes a solid
- 16. when particles move fast, are far apart, and do not touch unless they collide
