Earth’s spheres

  1. 1. Earth’s Spheres
  2. 2. Introduction <ul><li>There are three main “spheres” on earth </li></ul><ul><ul><li>Atmosphere </li></ul></ul><ul><ul><li>Hydrosphere </li></ul></ul><ul><ul><li>Lithosphere </li></ul></ul>
  3. 3. Atmosphere <ul><li>__________- is a thin envolope around the earth kept in place by gravity and is made of gas, liquids, and solids </li></ul><ul><li>It reaches from the earth’s surface up until space </li></ul><ul><li>It is the less dense out of the three main spheres </li></ul>
  4. 4. Atmosphere <ul><li>The atmosphere is stratified into zones each with it’s own characteristics </li></ul><ul><ul><li>Troposphere </li></ul></ul><ul><ul><li>Stratosphere </li></ul></ul><ul><ul><li>Mesosphere </li></ul></ul><ul><ul><li>Thermosphere </li></ul></ul>
  5. 5. Atmosphere troposphere Startosphere Mesophere Thermosphere
  6. 6. Troposphere <ul><li>____________- is the lowest region of the atmosphere the temprature decreases as the altitude increases </li></ul>
  7. 7. Stratopshere <ul><li>Part of the atmosphere that is right above the troposphere </li></ul><ul><li>As the altitude goes up so does the temperature </li></ul><ul><ul><li>This is due to the ozone </li></ul></ul>
  8. 8. Mesosphere <ul><li>Is above the stratosphere </li></ul><ul><li>As the altitude goes the temperature decreases </li></ul>
  9. 9. Thermosphere <ul><li>Outermost part of the atmosphere </li></ul><ul><li>At the altitude goes up so does the temperature </li></ul>
  10. 10. Hydrosphere <ul><li>Is the second sphere of the earth </li></ul><ul><ul><li>It covers ¾ of the earth’s surface </li></ul></ul><ul><ul><li>This includes all bodies of water </li></ul></ul><ul><ul><li>HYDRO – water </li></ul></ul>
  11. 11. Lithosphere <ul><li>Most solid part of the earth is the rock near the earth’s surface and is continues solid shell </li></ul><ul><li>It is even under the hydrosphere </li></ul><ul><li>It accounts for mountains faults etc.. Even under the ocean </li></ul>
