1. Title: Introduction to the aTmosphere
EQ: How are the layers of the atmosphere different?

2. Everyday is a holiday!
National Cake day!

3. A. Weather is a System
Definition- the state of Earth’s atmosphere at a particular time and place.
Includes:
a. types of clouds
b. precipitation (rain, snow, sleet)
c. storms, even dust storms
d. moisture in air
e. air pressure
f. wind direction

4. The study of weather and the atmosphere is what branch of Earth Science?
Meteorology

5. Give your best definition of WEATHER
Give your best definition of WEATHER! “the state of Earth’s atmosphere at a particular time and place.”

6. “Red sky at night, sailors delight
Red sky in the morning, sailors warning”

7. Air Pressure- weight of air Humidity- amount of moisture
Self Weathercasters
Air Pressure- weight of air
Changes in air pressure causes ears to pop
Old people say their bones ache.
Humidity- amount of moisture
in the air
Increased humidity makes hair wavy & curly
Skin feels moist

8. B. Weather Scales a.) shows frostbite potential
1. Wind chill Scale= actual temp. vs temp. with wind
a.) shows frostbite potential
b.) frost bite- “frozen body tissue”

10. There are four degrees of frostbite.
This is and example of fourth degree frost bite where only amputation of the affected area will save the patient.

11. C. Composition of the Atmosphere
Nitrogen- most abundant gas= it’s stable
Oxygen- 2nd most abundant
Carbon Dioxide- used by plants
Water vapor- produces clouds & rain
Draw in Notes!

12. D. Structure of the Atmosphere
1. Different layers are defined by their temperatures.

13. a. Troposphere- “changing”
1. Temperature cools as elevation increases.
2. Earth’s clouds and weather occur.
3. High amount of density = high air pressure & air mass

14. What is the main difference that defines the layers of the Atmosphere
What is the main difference that defines the layers of the Atmosphere? *different temperatures!

15. Why is the air pressure the HIGHEST in the troposphere
Why is the air pressure the HIGHEST in the troposphere? Higher air density (more air molecules for gravity to act on).

16. Why isn’t there more Carbon Dioxide in the air
Why isn’t there more Carbon Dioxide in the air? *Being used by plants & stored in water systems/animals

17. b. Stratosphere- “layers” 1
b. Stratosphere- “layers” 1. contains ozone layer (absorbs energy), causes temp. to increase with altitude

18. c. Mesosphere: ‘meso’- middle a
c. Mesosphere: ‘meso’- middle a. Temperature cools as elevation increases. b. Friction of gases protects Earth from meteoroids

19. d. Thermosphere- “heat” a
d. Thermosphere- “heat” a. absorbs a high amount of solar radiation = Temp. increases with altitude b. Northern lights (Auroras) c. Ionosphere- UV light from the sun causes gas molecules to become electrically charged particles (Ions)….. Provides radio communication!

20. Northern Lights- Aurora Borealis

21. Layers of the Atmosphere

22. Layers of the Atmosphere Mural
Materials:
Red text
Ruler
Colored pencils
Mural & Graph Packet

23. 2.) Exosphere- “outer” portion, extends toward space.

24. E. Importance of the Atmosphere
Stable environment
Protection- sun & meteoroids
Warmth- water can exist as a liquid

25. Greenhouse Gases: water vapor, CO2, methane

26. Beaufort scale self-cast Assignment
Purpose : Learn to use a Meteorological scale to help forecast the weather.
Obtain the Beaufort scale handout.
Complete the scale drawings and descriptions. Make sure that all sketches are colored with detail.
Use pg in the black text as a resource.

28. B. Weather Scales & Models
1. Beaufort Scale- relates wind speed to the effects of land and sea.

29. Quiz 3 Template Know gasses that make up atmosphere.
What layer contains the ozone?
What layer does weather occur in?
What is the BASIS for the division of atmosphere layers?
What layer do you live in?
What layer is responsible for the break up of meteors?
Order the layer from lowest to highest. (place a arrow by each layer to represent whether temp. increases or decreases.)
8. Know the three greenhouse gases. & how the greenhouse effect works

30. “The Atmosphere” Video Questions

Describe Bill’s “atmosphere cylinder” experiment, & what were his findings?
How do pilot’s determine their current altitude?
Describe the difference of air pressure between Death valley & on top of a mountain. Why the difference?
Why do your ear’s pop in a plane?
Order the five layers of the atmosphere from highest to lowest.
