  1. 2. A landform made of sediment that is deposited where a river flows into an ocean or lake.
  2. 5. A hole sunk into the ground to reach a supply of water.
  3. 7. A process in which mapmakers determine distances and elevations using instruments and the principles of geometry.
  4. 9. The portion of the hydrosphere that is frozen, including all the ice and snow on land, plus sea and lake ice.
  5. 10. A hill of sand piled up by the wind.
  6. 11. An exact copy of something on a much smaller scale.
  7. 12. An underground layer of rock or sediment that holds water.
  8. 15. A loop in which a signal or action triggers another signal or action.
  9. 17. A line that forms the boundary between the lake and the ocean or a lake.
  10. 18. A series of changes that happen over time and lead to an expected result.
  11. 19. The portion of Earth that consists of water in any of its forms, including oceans, glaciers, rivers, lakes, groundwater and water vapor.

  1. 1. The land area that supplies water to a river system.
  2. 3. The relatively thin layer of gases that forms Earth's most outermost layer.
  3. 4. The parts of Earth that contain living organisms.
  4. 5. The continual movement of water among Earth's atmosphere, oceans, and land surface through evaporation, condensation, and precipitation.
  5. 6. A group of parts that work together as a whole.
  6. 8. A landform with high elevation and high relief.
  7. 13. The process by which water molecules at the surface of a liquid absorb enough energy to change to a gas.
  8. 14. A natural stream of water that flows into another body of water, such as an ocean, lake or another river.
  9. 16. The ability to do work or cause change.
  10. 21. The shape of the land determined by elevation, relief, and landforms.
  11. 22. A feature on the surface of Earth such as a coastline, dune or mountain.
  12. 25. The process by which water is lost through a plant's leaves.
