  1. 3. The slow change of liquid water into gas at the surface, without boiling.
  2. 4. Water that falls from the atmosphere to Earth in the form of rain, snow, sleet, or hail.
  3. 5. Water from precipitation that flows over the ground and collects in rivers, lakes, and oceans.
  4. 8. The temperature at which a solid changes to a liquid; for water, 0°C (32°F).
  5. 10. A high-energy state of matter where gas particles become charged (ions); found in lightning, stars, and the Sun.
  6. 13. The process where a solid changes directly into a gas without becoming a liquid first.
  7. 14. The temperature at which a liquid changes to a gas; for water, 100°C (212°F) at sea level.

  1. 1. The process where water vapor (gas) cools and changes back into liquid water.
  2. 2. The process where plants release water vapor into the air through their leaves.
  3. 6. The temperature at which a liquid changes to a solid; for water, 0°C (32°F).
  4. 7. A state of matter where particles are tightly packed and have a definite shape and volume.
  5. 9. A state of matter where particles are far apart and move freely; gases have no definite shape or volume.
  6. 11. A state of matter where particles are close together but can move past each other; liquids have a definite volume but take the shape of their container.
  7. 12. The continuous movement of water on Earth through evaporation, condensation, precipitation, transpiration, and run-off.
