Environmental Science Chapter 2 Section 1

  1. 1. Environmental Chapter 2
  2. 2. Biogeochemical Cycles <ul><li>Most things in nature get recycled and are used over again </li></ul><ul><li>Three common cycles </li></ul><ul><ul><li>Water cycle </li></ul></ul><ul><ul><li>Carbon cycle </li></ul></ul><ul><ul><li>Nitrogen cycle </li></ul></ul>
  3. 3. The Water Cycle <ul><li>Water moves through the biotic and abiotic factors in the environment </li></ul><ul><li>Ways water can move: </li></ul><ul><ul><li>Precipitation </li></ul></ul><ul><ul><ul><li>water moves from the atmosphere to the land in the form of snow, rain, sleet and hail. </li></ul></ul></ul><ul><ul><ul><li>During evaporation and transpiration (evaporation from plants and through skin) water cools and condenses, precipitation forms </li></ul></ul></ul><ul><ul><ul><li>About 91% falls into oceans. The rest falls on land to replenish the fresh water supply </li></ul></ul></ul>
  4. 4. <ul><ul><li>Evaporation </li></ul></ul><ul><ul><ul><li>Water moves from the land to the atmosphere </li></ul></ul></ul>
  5. 5. <ul><ul><li>Ground Water – when precipitation seeps into the ground and becomes part of the water table </li></ul></ul>
  6. 6. <ul><ul><li>Runoff </li></ul></ul><ul><ul><ul><li>Water that flows on top of the ground </li></ul></ul></ul>
  7. 8. The Carbon Cycle <ul><li>All living things have carbon in them </li></ul><ul><li>All carbon that is on earth has been here since the earth was formed </li></ul>
  8. 9. Ways that carbon moves through the environment <ul><li>Photosynthesis – carbon gets taken out of the air and used by producers to make food </li></ul><ul><li>Respiration- carbon gets put back into the air by animals when they exhale </li></ul><ul><li>Decomposition – breakdown of dead materials by bacteria and fungi </li></ul><ul><li>Combustion – carbon in fossil fuels is released while burning </li></ul>
  9. 11. The Nitrogen Cycle <ul><li>78% of the earth’s atmosphere is nitrogen </li></ul><ul><li>Organisms cannot use nitrogen directly from atmosphere </li></ul><ul><li>Nitrogen fixation- when bacteria in the soil change atmospheric nitrogen gas into usable nitrogen </li></ul><ul><li>Lightening can also fix nitrogen </li></ul><ul><li>Denitrification-different bacteria change usable nitrogen into atmospheric nitrogen gas </li></ul>
