atmosphere

Earth’s Atmosphere is

•A thin layer of gases that surrounds the Earth•A protective layer from the Sun’s

ultraviolet radiation due to Ozone in the stratosphere•Divided in layers based upon

temperature variations

•Do Now: Take out ESRT and open to page 14. In your notebook, summarize what you learned by graphing the various atmospheric layers vs. their temperature. After you complete this see the directions that follow.Directions: Check off as you complete!

• 1._____Using a highlighter, highlight the 4 layers of the atmosphere2._____Highlight the x-axis and the y-axis3._____Circle the three headings- Temperature zones, Atmospheric pressure, and Water vapor

• Answer the following:1. State the temperature ranges for theTroposphere_______to____________

• Stratosphere_______to___________

• Mesosphere_______to____________

• Thermosphere______to____________

2.. List the boundaries (or interfaces!):__________________________________

3. What is the atm pressure 10km up?___________________

4. What is the water vapor concentration at sea level?_________________Why?_________________________________________________

5.What is the temperature at the interface between the troposphere and the stratosphere?__________________

6.Which layer do we live in?_________________________

7. Which layer do airplanes fly in?______________________

State one conclusion below based on the information in this chart:

• Think about (It Says…I Say…And So…)• 1. What does the chart say?

• 2. What do I know or say?• 3. Combine the information in the chart and what you know to

come up with your inference…and so

Make a chart in your notes…if it helps

o The Ozone Hole is recreated everySpring at the South Pole as the windsdie down.o It formed due to chlorofluorocarbons orCFC’so The Montreal Protocolwas an international treaty signed to protectthe Ozone layer in 1981

The Northern Lights or the Aurora Borealis

Wrap up: Knowing what you know now about the earth’s atmosphere, infer how the sun pillar formed in the picture below:

From EPOD:• This eye-catching Sun

pillar appeared just at sunset on July 27, 2014 as observed from Ranchos, Buenos Aires, Argentina. The recipe for pillars is quite simple: First, hexagonal ice crystals are required -- found in high clouds or free falling through the atmosphere; second, nearly all of these crystals must be aligned similarly and tipped a bit; sunlight is then reflected off the crystals in the viewer's direction. Only on occasion, however, are pillars observed extending 10 degrees or more above the horizon, such as the one above.
