  2. 3. the process by which water is transferred from the land from surfaces and plants. (18)
  3. 4. water which is moving through the soil. (11)
  4. 5. the movement of water from the soil into the bedrock. (11)
  5. 8. a stream which flows into a larger river. (9)
  6. 11. the boundary between drainage basins; it is often a ridge of high land. (9)
  7. 12. the starting point of a river; it may be a lake, glacier or marsh. (6)
