|EXOSPHERE: This is the outermost layer which stretches to 5,500 miles from the Earth. The air is very thin because the air particles are widely separated. Beyond the Exosphere lies outer space, where there are almost no air particles. There is no weather in the Exosphere.|
|THERMOSPHERE: Once called the Ionosphere, this layer extends beyond the Mesosphere (our next layer) to the beginnings of outer space found in the Exosphere. Here solar energy boosts the temperatures to a maximum of 3,600 degrees Fahrenheit. It extends 250 miles beyond the Mesosphere.|
|TROPOSPHERE: This is the layer nearest the earth. It ranges from 5 to 11 miles in thickness. All of our weather takes place within this layer.|
