Transcript of "The atmosphere and the oceans"

  1. 1. 11. Atmosphere 12. Meteorology 13. The Nature of Storms 14. Climate15. Physical Oceanography16. The Marine Environment
  2. 2.  Section 11.1 ◦ Describe the composition of the atmosphere ◦ Compare and contrast the various layers of the atmosphere ◦ Identify three methods of transferring energy throughout the atmosphere
  3. 3.  The composition, structure and properties that make up Earth’s atmosphere How solar energy, which fuels weather and climate, is distributed throughout the atmosphere. How water continually moves between Earth’s surface and the atmosphere in the water cycle
  4. 4.  Understanding Earth’s atmosphere and its interactions with solar energy is the key to understanding weather and climate, which control so many different aspects of our lives. In what ways does weather effect what you do from day to day?
  5. 5.  How does dew form on the surface? Summary: Dew forms when moist air near the ground cools and the water vapor in the air changes into water droplets. Can you give another example when this occurs?
  6. 6.  Atmospheric Composition ◦ Air is a combination of many gases  99% = nitrogen and oxygen (life could not exist without these gases)  1% = argon, hydrogen, carbon dioxide, water vapor and other gases Percentages of Gases That Make Up Earths Atmosphere Nitrogen Oxygen Other
  7. 7.  Water vapor can vary from place to place and is important because it can effect the amount of clouds, rain or snow that we have. The amount of water vapor in the air depends on: ◦ Seasons ◦ Altitude ◦ Surface features beneath the air
  8. 8.  Dust and salt is also found in the atmosphere ◦ Dust is brought into the atmosphere through wind ◦ Salt is picked up from spray in the ocean These two substances contribute to the formation of clouds also. Answer this: When you reach out and grab a handful of air why can’t you see the dust, salt, water vapor and other substances?
  9. 9.  Take notes on facts you learn as you watch this movie In Summary ◦ Ozone exists in small quantities well above the Earth’s surface. ◦ It absorbs ultraviolet radiation from the sun which our skin can’t tolerate for very long. ◦ Evidence shows that the Ozone layer is getting thinner.
  10. 10.  On a separate sheet a paper answer the following questions  Where is the Ozone Layer?  How does it help us?  Name three things that can cause holes in the Ozone layer.  How do ultraviolet rays cause problems for humans?  What can we do to protect ourselves from ultraviolet rays?
  11. 11.  TROPOSHPHERE ◦ The layer closest to the Earth’s surface. ◦ Contains most of the mass of the atmosphere ◦ Most weather takes place here and most pollution collects here ◦ There is a decrease in temperature from the bottom to the top ◦ The top limit of the troposphere is called the tropopause where the gradual decrease in temperature stops
  12. 12.  STRATOSPHERE ◦ Above the tropopause ◦ Primarily made up of concentrated ozone so the stratosphere is heated and gradually increases in temperature until the top layer called the stratopause.
  13. 13.  MESOSPHERE ◦ Above the stratopause ◦ Decrease in temperature begins again since there is no concentrated ozone in this layer ◦ The top of the mesosphere is called the mesopause THERMOSPHERE ◦ Very little air exists in this part of the atmosphere ◦ The temperature increases by 1000 degrees centigrade, but we don’t feel it because the molecules that make up the air are few and spread out
  14. 14.  EXOSPHERE ◦ Outer most layer of the atmosphere (outer space) ◦ Contains light gases: hydrogen and helium A REVIEW OF ATOMOSPHERIC LAYERS
  15. 15.  The sun is the source of all energy in the atmosphere. This energy is transferred to Earth and throughout the Atmosphere in three ways:
  16. 16.  Radiation is the transfer of energy through space by visible light, ultraviolet radiation, and other forms of electromagnetic waves.  This occurs because the sun is constantly warming a place on earth at all times. Only 50% of the radiation that comes to earth is actually absorbed on the surface  35% of it bounces back by reflecting from the surface, atmosphere or clouds  15% of it absorbed by the atmosphere (page 275) Why does the inside of a closed, parked car heat up, while the windows stay cool?
  17. 17. Why does life exist in only a small layer of the atmosphere?
  18. 18.  The process of transferring heat from one object to another. When talking about the atmosphere heat is passed on when the molecules collide. Think: What would happen if you held a metal rod over a flame. How is conduction related to cold air temperatures at the poles which are covered with ice and snow?
  19. 19.  The transfer of energy by the flow a heated surface. Pockets of air on the surface are heated, rises up in the atmosphere which causes it to cool, fall and become heated again. Convection currents are one reason for change in weather.
  20. 20. Use this picture to describe the threemethods by which solar energy that reachesthe earth is transferred.
  21. 21.  What have you learned this section  The Earth’s atmosphere is made up of a combination of several gases that included nitrogen and oxygen.  The Earth’s atmosphere consists of several different layers that vary in temperature. Most of the weather happens in the troposphere. This where most of the mass happens.  The sun is the source of energy in Earth’s atmosphere. Solar energy (heat from the sun) moves through the atmosphere using radiation, conduction, and convection.
  22. 22.  Vocabulary ◦ Conduction (p. 276) ◦ Convection (p.277) ◦ Exosphere (p. 274) ◦ Mesosphere (p. 274) ◦ Ozone (p. 273) ◦ Radiation (p. 275) ◦ Stratosphere (p. 274) ◦ Thermosphere (p. 274) ◦ Troposphere (p. 274)
  23. 23.  Choose two of the following activities to show what you have learned: ◦ Answer the section assessment questions on p. 277 ◦ Develop a poster showing the different layers of the atmosphere and the different characteristics of each layer ◦ Make a concept map related to the main ideas in the section (use p. 934 in your book to help you) ◦ Ask for the “Exploring Environmental Problems” activity ◦ Complete the “Dew Formation” Lab (as Ms. P for the sheets to go with this)
  24. 24.  Section 11.2 ◦ Describe the various properties of the atmosphere and how they interact ◦ Explain why atmospheric properties change with changes in altitude
  25. 25.  Section 11.3 ◦ Explain how clouds are formed ◦ Identify the basic characteristics of different cloud groups ◦ Describe the water cycle
  26. 26.  The composition, structure and properties that make up Earth’s atmosphere How solar energy, which fuels weather and climate, is distributed throughout the atmosphere. How water continually moves between Earth’s surface and the atmosphere in the water cycle
  27. 27.  Understanding Earth’s atmosphere and its interactions with solar energy is the key to understanding weather and climate, which control so many different aspects of our lives. In what ways does weather effect what you do from day to day?
