THE ATMOSPHERE UNIT 2 CHAPTER 17 Poirier

Atmosphere Brainstorm  On page 18 or 19 in your INB list as many words as you can think of that  Describe  Influence  Affect  Result from  ….  The ATMOSPHERE

Graph Interpretation

Dynamic Earth

Earth The Biography: Atmosphere  Video  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 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 CO 2, SO 2, H 2 O, N 2  Photosynthesis changed this CO 2 to produce O 2  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 Does the amount of carbon dioxide remain constant throughout the year?

Atmospheric Pressure ? 50%

In what direction does air apply pressure?  Glass water index card demo

Structure of the Atmosphere  Divided into layers based on changes in temperature  Sketch this diagram Into your notebook on page 27

Word of Day Oct 5-9  Bizarre- grossly unconventional or unusual  Chronology- sequence of events (like relative time)  Deduction- remove part from a whole (like subtraction)  Ellipse – oval shaped (slightly flattened circle)  Flourish – grow vigorously (fast and healthy growth) Page 31 INB

Warm up  Which of the following is not a fossil fuel? A. Coal B. Wood C. Petroleum D. Natural Gas

Warm up  A volcanic eruption can affect the atmosphere by A. Reducing the amount of water vapor in the atmosphere B. Adding large quantities of several gases, such as SO 2, to the atmosphere C. Clearing away nearby clouds, increasing the amount of sunshine D. Increasing the amount of oxygen due to escaping gasses

Radiosonde

Temperature vs. Altitude Lab (Radiosonde Analysis Lab)  Where will our data come from?   B4NGi3bFr3BWGFYc_t0f-N&index=34 B4NGi3bFr3BWGFYc_t0f-N&index=34

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?
