Across
  1. 2. Falls between the two nutrient enrichment extremes
  2. 4. The natural conditions in which water reaches an aquifer
  3. 6. Outer area of floodplain
  4. 8. Fluctuation of water table as water seeps into Earth
  5. 9. Main channel of a river
  6. 10. Newly formed lake with a small supply of plant nutrients which makes it poorly nourished; deep and has steep banks
  7. 13. Composed mainly of decomposers and detritus feeders, dead matter mainly nourishes this zone
  8. 15. The sum of actual and rejected recharge
  9. 19. The acceleration of eutrophication in lakes due to human input of nutrients from agriculture, urban areas, and the atmosphere
  10. 20. Deep wells in which water is stored under immense pressure below impermeable rock layers
  11. 21. The filling of groundwater aquifers by precipitation percolating deep into the Earth and saturating the pores
  12. 22. Cavity formed where the water table sinks due to the pumping of groundwater
  13. 24. Gradual abrasion of land due to ice,wind and water
  14. 25. Water held in the saturated zone below the water table
Down
  1. 1. Away from the shore, sunlit water at the surface that extends to depths where sunlight penetrates, food and oxygen is produced here
  2. 3. Movement of saltwater into freshwater aquifers
  3. 5. Impermeable rock layer above aquifer stops water from seeping directly into ground
  4. 7. The process in which all layers in the lake mix bringing oxygen to the benthic zone and dead matter to the littoral zone
  5. 11. Human activities that assist in the recharging of water into aquifers
  6. 12. Area where water permeates directly from groundwater into aquifer
  7. 14. Moves wind counter clockwise in Southern Hemisphere and Northern to clockwise, caused by earth's rotation
  8. 16. Area around aquifer where precipitation replenishes groundwater
  9. 17. Area of deep open water, too dark for photosynthesis, low oxygen levels, cooler temperatures
  10. 18. Area of lake near the shore, shallow sunlit waters where rooted plants stop growing
  11. 23. Large amount of plant nutrients which makes it well-nourished and have a high net productivity; usually shallow and has murky green or brown water with poor visibility
