  2. 2. – water that falls to Earth as rain, snow, hail or sleet
  3. 3. – the process by which molecules at the surface of a liquid absorb enough energy to change to a gaseous state
  4. 5. Cycle – the continuous process by which water moves from Earth’s surface to the atmosphere and back driven by energy from the sun and gravity
  5. 6. – streams and smaller rivers that feed into a main river

  7. 10. molecule - a molecule that has electrically charged areas
  8. 13. – the place where an organism lives and obtains all the things it needs to survive
  9. 15. Table – the top of the saturation zone
  10. 16. – water that fills the cracks and spaces in soil and rock layers
