  2. 8. Downward movement of water from the surface into the soil.
  3. 9. Sides of a valley against which a dam rests.
  4. 11. Lateral movement of water within the unsaturated soil layer.
  5. 14. Liquid precipitation with droplet size between 0.5–6 mm.
  6. 15. Coating of smooth ice formed when freezing rain strikes cold surfaces.
  7. 16. Area draining rainfall to a common outlet or stream.
  8. 18. Diffusion: Movement of water vapor through air or porous media.
  9. 23. Very light rain with tiny droplets (<0.5 mm).
  10. 25. Line joining points of equal elevation on land.
  11. 26. Line: The boundary dividing two adjacent drainage basins.

  18. 35. Portion of rainfall that flows over land to streams and rivers.
Down
  1. 1. Conversion of liquid water into vapor due to heat.
  2. 2. Runoff: Flow of excess rainwater over the land surface.
  3. 3. Point: Common outlet where runoff from a catchment collects.
  4. 4. The amount of precipitation received over an area in a given time.
  5. 6. Flow: Movement of water through underground aquifers.
  6. 7. Loss of water vapor from plant leaves to the atmosphere.
  7. 10. Ice crystals formed by direct freezing of water vapor in clouds.
  8. 12. Rainwater caught by vegetation before reaching the ground.
  9. 13. Storage: Water temporarily stored in surface depressions after rain.
  10. 17. Physical features and surface shape of the land.
  11. 19. Any form of water falling from clouds to Earth’s surface.
  12. 20. Area: Land area that gets flooded when a reservoir fills.
