  4. 9. Impassable, not allowing passage through (such as by a liquid)
  5. 11. Water pollution that comes from a single identifiable location (e.g., pipes, ditches, channels, sewers, tunnels, containers of various types).
  6. 14. The land area that supplies water to a river system.
  7. 16. The first deep-sea submersible capable of carrying passengers, usually a pilot and two observers.

  9. 19. The entire geographical area drained by a river and its tributaries
  10. 21. The ability of a rock or sediment to let fluids pass through its open spaces, or pores.
  11. 23. The change of state from a liquid to a gas (Puddle)
  12. 25. The continuous process by which water moves from Earth's surface to the atmosphere and back
  13. 26. the water that is beneath Earth's surface
  14. 28. nitrogen compounds used for growth by plants and algae
  15. 29. Evaporation of water from the leaves of a plant
  16. 31. water that is safe to drink
Down
  1. 1. water that is safe for bathing/cleaning, but not drinking
  2. 3. An underwater vehicle built of strong materials to resist pressure.
  3. 4. Part of the water cycle where an excess of water runs down and does not sink into the soil and eventually makes it to the rivers, lakes, and oceans.

  6. 8. water pollution that does not have a specific point of origin
  7. 10. A process by which nutrients, particularly phosphorus and nitrogen, become highly concentrated in a body of water, leading to increased growth of organisms such as algae or cyanobacteria.

  16. 27. A measure of how hot (or cold) something is; specifically, a measure of the average kinetic energy of the particles in an object.
  17. 30. Sound Navigation and Ranging - Used to find and identify objects in water using sound waves. It is also used to determine water depth (bathymetry).
