Layers of the Atmosphere To use in conjunction with graph Activity

Directions PACKET IS DUE ON FRIDAY Read through the layers. Summarize important information for each layer. Color in the key for layer (see board). Complete the graph. Answer the analysis questions.

Graph USE THE CHECKLIST. DO IT IN PENCIL. You’ll make mistakes. Need a title and Axis Labels with units. X = Temperature (ºF) Y= Altitude (miles) For the X Axis, each line will represent 30 ºF  Start at - 160 on the left, end with 710 on the right Make sure you have everything stated in the directions.

Layers Exosphere Thermosphere Mesosphere Stratosphere Troposphere

In between are the pauses Pauses mark the upper limit of the layer Tropopause Stratopause Mesopause Thermopause

Troposphere Layer closest to Earth Heat here is due to the IR released from the Earth Weather & 99% of water vapor seen here Most dense layer Ends in the Tropopause

Stratosphere 2nd layer  starts at the tropopause Airplanes & weather balloons found here Ozone Layer is in the stratosphere Protects us from UV rays (cause cancer) Ends with Stratopause

Mesosphere Strat Troposphere

Mesosphere 3rd Layer from Earth Meteors burn up in this layer Due to the friction between the air molecules and the meteor Ionosphere starts here (made of ions) Ends in Mesopause

NOCTILUCENT CLOUDS

Thermosphere 4th Layer Low density& thin air Space satellites orbit here Very hot here  a lot of UV is absorbed Where we find the Aurora Borealis (Northern Lights)

Aurora Borealis/Australis Charged solar particles react with the O2, N2 in the atmosphere  Found over the poles of the Earth

Ionosphere- bounces radio waves around - Made of ions (charged particles) - From the sun splitting atoms

Exosphere Extremely low density (particles far apart)  air is thin Gradually fades into outer space No exopause Made mostly of Helium (He) and Hydrogen (H)

Let’s go over the graph and the analysis questions.
