Across
- 4. – the process by which nutrients build up in a lake causing the algae to grow rapidly
- 5. – the land area that supplies water to a river system
- 7. – does not allow water to pass through easily because it has few or no pores or cracks.
- 9. action - the combined force of attraction among water molecules and with the molecules of the surrounding materials
- 11. - a mixture that forms when one substance is dissolved in another
- 12. System – a river and all of its tributaries together
- 14. – allows water to pass through because they have large and connected pores
- 17. Zone – a layer that contains air as well as water that has soaked into the ground
- 18. – a land area that is covered with a shallow layer of water during some or all of the year
- 19. – an underground layer of permeable rock that holds water and allows it to flow
Down
- 1. Zone – a layer where the pores in the ground are filled with water
- 2. – water that falls to Earth as rain, snow, hail or sleet
- 3. – the process by which molecules at the surface of a liquid absorb enough energy to change to a gaseous state
- 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
- 6. – streams and smaller rivers that feed into a main river
- 8. – when plants give off water vapor through their leaves
- 10. molecule - a molecule that has electrically charged areas
- 13. – the place where an organism lives and obtains all the things it needs to survive
- 15. Table – the top of the saturation zone
- 16. – water that fills the cracks and spaces in soil and rock layers
