Earth’s Atmospheric Layers

Troposphere Weather and clouds occur in this layer Water vapor and carbon dioxide (CO2) are also found in this layer and are important in the weather conditions As altitude increases, temperature decreases Airplanes fly here Extends from the surface of Earth up to 6-20km

Stratosphere The ozone layer is contained here https://www.youtube.com/watch?v=7f-K-XnHi9I The ozone layer is contained here Ozone is a form of oxygen that is found in this layer The temperature is cold except in the upper region where ozone is located Weather balloons can fly up to the stratosphere Extends from 20 to 50 km

Mesosphere This is the coldest layer Meteors, or shooting stars, burn up in the mesosphere because of the interaction with the Earth’s atmospheric layers Extends from 50 up to 85 km Mesosphere

Thermosphere This is the warmest layer The air is very thin in this layer The ionosphere can be found in the lower portion of the thermosphere -the Northern Lights, also called Aurora Borealis, occur here as well Shuttles orbit here Extends from 86 up to 690 km

Exosphere Cold regions of outer space extend from this layer Satellites orbit here Extends from 691 up to 10,000 km There is no clear definition of where outer space begins, but we generally use the measurements of 80-128 km from Earth Exosphere
