1 Earth’s Atmospheric Layers

2 Troposphere Distance above sea level: 0-16 km Average Temperature: -50º to 70º F All weather happens here. Warm air rises to form clouds, rain falls. As altitude increases, temperature decreases. (The higher you go the colder it gets) Warmed by the ground below

3 Troposphere 80% of the total atmospheric mass 99% of Earth’s water vapor Air pressure the highest Layer nearest Earth’s surface All life exists here. This is where we live!

4 Stratosphere Distance above sea level: 16-50 km Average temperature: -50º to 0º Ozone layer located at the top of this layer. Gets warmer as you go up in the layer: ozone absorbs radiation from the sun, which makes it hotter. As altitude increases, temperature increases

5 Stratosphere Jets cruise near the bottom of this layer Less than 20% of the total atmospheric mass Warmer than the troposphere Clear, dry layer Weather balloons are flown to this layer.

6 Mesosphere Distance above sea level:50-90 km Coldest layer Average temperature: 0º to -90º F Gets colder as you go up: decrease in ozone gas Heated from below (ozone layer) As altitude increases, temperature decreases Meteors or shooting stars burn up

7 Mesosphere Less than 1% of the atmospheric mass Hardest to study since planes can’t fly high enough and satellites can’t fly low enough Extremely thin air

8 Thermosphere Distance above sea level: 90-300 km Average temperature: -90º to 120º F Hottest layer of the atmosphere Gets warmer as you go up: closer to the sun As altitude increases, temperature increases Shimmering curtains of light called auroras happen there

9 Thermosphere Space shuttles orbit at this layer Less than 1% of the atmospheric mass Near a vacuum so not enough contact with atoms of gas to transfer much heat

10 Exosphere Distance above sea level: 300-600 km Average temperature: Extreme highs and extreme lows Temperature begins to level off Many satellites orbit at this layer Less than 1% of the atmospheric mass Sometimes considered as part of outer space Air pressure the lowest
