Biogeochemical Cycles. 12/6/11. What are biogeochemical cycles?. Biogeochemical cycles= complete path a chemical takes through the atmosphere, hydrosphere (water), lithosphere(earth’s crust and mantle) and biosphere (plants and animals) Bio= life Geo=earth Chemicals= elements and compounds.

Presentation Transcript
what are biogeochemical cycles
What are biogeochemical cycles?
  • Biogeochemical cycles= complete path a chemical takes through the atmosphere, hydrosphere (water), lithosphere(earth’s crust and mantle) and biosphere (plants and animals)
    • Bio= life
    • Geo=earth
    • Chemicals= elements and compounds
what is the rock cycle
What is the rock cycle?
  • Sedimentary
  • Igneous
  • Metamorphic
what is the hydrologic cycle
What is the Hydrologic Cycle?
  • The water Cycle
    • Precipitation
    • Evaporation
    • Transpiration
    • Condensation
what is carbon cycling
What is carbon cycling?
  • Food Chain
  • Decomposition
  • Carbon emissions
what is nitrogen cycling
What is Nitrogen Cycling?
  • Nitrogen fixation: N2NH4 NO2  NO3
  • Factory emissions and Eutrophication
what is phosphorus cycling
What is Phosphorus Cycling?
  • Minerals/Soil
  • Fertilizer run off, sewage
do humans effect biogeochemical cycling
Do humans effect biogeochemical cycling?
  • Humans are responsible for nearly half the fixed nitrogen that is deposited on land.
  • Fossil Fuels release carbon emissions when burned  greenhouse gases
  • Sulfur, phosphorus and Nitrogen released through mining and deforestation
how are the nitrogen phosphorus and carbon cycles linked
How are the Nitrogen, Phosphorus and Carbon cycles linked?
  • Nitrogen is found in chlorophyll, phosphorus is taken up from soil into plants, which enter the food chain (carbon cycle).
