QUESTIONS Atmosphere 1 List the four main layers

QUESTIONS Atmosphere 1. List the four main layers of the atmosphere (in order of increasing altitude): 2. Which major layer has TWO minor layers (name them, too). 3. Which layer is the most important to you? WHY? 4. Explain how each layer protects you. 5. Where is the ozone layer located? 6. What happens to temperature as you go higher in the troposphere? In the stratosphere? Name: _______ Period: ___ Layers of the

Instructions Occurrences 1. 2. 3. Blackbird (military ops) - 26 km 4. 5. 6. 7. 8. Cut your blue sheet along the center Glue ends onto white sheet of paper Color the graph to indicate temperature changes (getting hotter = red, getting colder = blue) Cut the front to make flaps for each of the major layers. Cut out the boxes on this page that contain the characteristics of each layer. Paste them inside the shutters under the correct layer. (Put main layers under the left doors and minor layers under the right doors). For the occurrences in the second column, paste the symbol for each and place them at the appropriate altitude on the FRONT of the foldable. Answer the questions on the back of the foldable. Write your name on the back. Boeing 747 - 12 km Ozone molecules – 20 to 30 km Aurora Borealis – 100 to 250 km Int’l Space Station - 300 km Flock of Geese - 6 -7 km Weather – surface Cirrus clouds – 16 km Cumulonimbus – up to 16 km Radio Waves – 96 to 112 km Meteors- 48 to 80 km Unmanned spacecraft – 3000 km MAGNETOSPHERE Characteristics: 1. Earth’s magnetic field 2. Causes Aurora Borealis (Northern Lights) TROPOSPHERE Temp: DECREASES 6. 5° per km to about - 60° C Characteristics: 1. Most weather occurs here (where we live) 2. Convection currents STRATOSPHERE Temp: INCREASES to about - 20° C Characteristics: 1. Contains most of atmosphere’s ozone 2. Where jets & manned balloons have gone MESOSPHERE Temp: DECREASES, - 100° C at top Characteristics: 1. Protects earth from meteors 2. Coldest region of atmosphere THERMOSPHERE Temp: INCREASES to 2000° C at top Characteristics: 1. Temperatures get up to 2000° C 2. Air molecules are 1 km apart! OZONOSPHERE Characteristics: 1. Ozone is made of 3 oxygen atoms 2. Protects the surface from Sun’s UV rays 3. Humans are causing ozone depletion IONOSPHERE Characteristics: 1. Lower part of thermosphere 2. Radio waves bounce back to earth’s surface EXOSPHERE Characteristics: 1. Upper part of thermosphere 2. Artificial satellites orbit here
