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