  1. BIOGEOCHEMICAL CYCLES

  2. Biogeochemical Big word; simple idea • Bio = life • Geo = earth • Chemical = substance So biogeochemical = substances involved with life on earth.

  3. Water Cycle

  4. Water Is Everywhere • 75% of the earth’s surface is covered with water. • All living things contain water. • There is water in the atmosphere.

  5. Water on the Move • Water continually cycles from the earth to the atmosphere and back again.

  6. Evaporation • Water evaporates (changes from a liquid to a gas).

  7. Condensation • Water condenses (changes from a gas to a liquid).

  8. Precipitation • Water returns to earth’s surface in the form of rain, sleet, snow or hail.

  9. The Very Simple Version Condensation Precipitation Evaporation

  10. It’s more complicated than that.

  11. Transpiration • Plants return water to the atmosphere. Plant loses water through leaves Plant sucks in water through roots

  12. Perspiration • Animals return water to the atmosphere when they sweat, pant, breathe, etc.

  13. Infiltration • Water goes into the ground. It filters through soil, rocks, etc. Diagram courtesy of the U.S. Geological Survey

  14. Runoff • Some water moves along the surface of the ground collecting in low areas. Diagram courtesy of the U.S. Geological Survey

  15. Ground Water • Water filters into soil and rock until it comes to rocks it cannot pass through. • Water may fill spaces in rocks and soil. • An aquifer is a pool of underground water.
