  3. 6. – water that fills the cracks and spaces in soil and rock layers
  4. 11. – a layer that contains air as well as water that has soaked into the ground
  5. 15. – the land area that supplies water to a river system
  6. 17. – does not allow water to pass through easily because it has few or no pores or cracks.

  10. 14. – a river and all of its tributaries together
  11. 15. – the continuous process by which water moves from Earth’s surface to the atmosphere and back driven by energy from the sun and gravity
