Read through questions on your hand out

Complete as you watch

Warm up on page 18

What is the greenhouse effect? What are the greenhouse gasses? Where do they come from?

Atmosphere video worksheet - discuss with lab group

Switch worksheets with someone in your group

Read through their answers and assign a grade #/30

Take 5 minutes to try to get

everyone’s paper to a 30/30

Use only YOUR – Earth the Biography-Atmosphere notes page

When complete turn in get a textbook (518 & 519) and work on guided notes

Open Note Video Quiz

Read Text pages 518-519 and supplemental sheet (must return)

Complete the guided notes handout

Do not use marker on your circle chart

Remember “pie slices” (circle chart) are “cut” from a center point

Check your notes

Take any additional notes on page 25 in your notebook

Composition of Atmosphere

Has changed over Earth’s history

Early atmosphere volcanic in origin CO2, SO2, H2O, N2

Photosynthesis changed this CO2 to produce O2

Current atmosphere Nitrogen ~78% Argon & water vapor ~1% Oxygen ~21% Carbon dioxide & trace

others ~.03%

Composition is ~ Stable

Due to recycling of atmospheric materials Atmosphere/geosphere/hydrosphere

Water cycle

Carbon – Oxygen cycle

Nitrogen cycle

Carbon dioxide http://www.esrl.noaa.gov/gmd/ccgg/carbontracker/

Does the amount of carbon dioxide remain constant throughout the

year?

Atmospheric Pressurehttp://www.physicalgeography.net/fundamentals/7d.html

? 50%

In what direction does air apply pressure?

Temperature vs. Altitude Lab

Read and follow through directions as Mrs. P demonstrates

You will work in pairs – one computer – both need to record answers.

Carefully read and follow directions

Review Atmospheric Structure Memory device?

Where is the ozone layer?

Which layer contains 80% of the mass of the atmosphere?

Which two layers show an increase in temperature with an increase in altitude? Why?

Where does weather occur?
