  1. Earth’s atmosphere 5/29/13

  2. Do Now: On a piece of paper to be handed in: • 1. Name all the 5 layers of the atmosphere from lowest to highest in elevation. • 2. How did Earth’s ancient atmosphere form?

  3. Earth’s atmosphere • Atmosphere is a thin layer of gases surrounding Earth.

  4. Why is Earth’s Atmosphere important? • It contains oxygen, carbon dioxide, and water for life. • It regulates the temperature within a range for organisms to survive in. • It protects organisms from harmful rays and meteor strikes.

  5. Where did the Earth’s Atmosphere come from? • Volcanos released hot gas that surrounded ancient Earth and created the atmosphere. • Most of the atmosphere was only water vapor and carbon dioxide. Which types of organisms were able to survive in this type of atmosphere? • Plants were able to perform photosynthesis and release oxygen into the atmosphere.

  6. Today’s Atmosphere

  7. Layers of the atmosphere

  8. Air pressure • How does air pressure change as altitude increases?

  9. Into thin air by Jon Krakauer • Mt. Everest is the highest mountain. 8,848 meters • Over 200 people have died trying to climb it. • https://www.youtube.com/watch?v=hwK1doSx1R8 • Which layer of atmosphere is Mt. Everest located?

  10. Card sort game • Find the two labels: LAYER and DESCRIPTION • You must have the layers in order from lowest elevation to highest elevation. • Sort the cards to match the descriptions with the correct layer. • First team to finish and have their cards sorted correctly wins a small prize!

  11. Layers of the atmosphere • Troposphere (surface to 15km): • This is the layer that is closest to Earth. • Warmest part of the troposphere is near Earth’s surface. • Stratosphere (15km to 50km): • This is where the ozone layer is located. • This layer absorbs harmful UV rays from the sun. • Mesosphere(50km to 85km)/Thermosphere(85km to 500km): • Meteors burn up in this layer. • Radio waves travel long distances in this layer. • Ions from the sun strike air molecules to form auroras. • Exosphere (above 500km): • Pressure and density are extremely low. • Air molecules can escape to space.
