Across
  1. 1. cycle in which its reservoir is the air or the oceans
  2. 7. subsurface reservoir of fresh water
  3. 8. part of the sedimentary cycle where other salts deposit out as sediment and rock in shallow seas
  4. 10. another term for living things
  5. 14. product of condensation of atmospheric water vapor that falls on the ground
  6. 15. used in agriculture, which are then washed into lakes, streams, and rivers surface runoff
  7. 17. the main oxygen generators of the biosphere
  8. 18. water inside living things
  9. 19. another term for reservoir
  10. 22. the second most abundant element in organisms
  11. 23. is a process that takes away mineral components from saline water
  12. 24. its use had accelerated in the 1800s during the industrial revolution
  13. 25. converts carbon dioxide gas to organic carbon
  14. 26. is returned to soil or water through decomposition of biomass or excretion by consumers
  15. 27. a place where something is kept in store
  16. 29. the process of water movement through a plant and its evaporation through aerial parts
Down
  1. 2. process of frozen water to water vapor by solar energy
  2. 3. is second only to nitrogen in abundance among uncombined elements in the atmosphere
  3. 4. the area of the Earth where water movement and storage occur
  4. 5. process of liquid water to water vapor by solar energy
  5. 6. cycle in which its reservoir is the Earth’s crust
  6. 9. a worlwide, major environmental concern caused by the excessive amount of carbon dioxide in the atmosphere
  7. 11. essential element for the molecules of living things
  8. 12. characterized by excessive plant and algal growth
  9. 13. contain 97.5% of water in the biosphere
  10. 16. cycles between the oceans, land, and atmosphere
  11. 20. process of water vapor into clouds
  12. 21. is a process of which sulfur is falling directly from the atmosphere
  13. 23. the process when bacteria converts the nitrates into oxygen gas
  14. 28. enters the living world through free-living and symbiotic bacteria
