The Stratosphere contains over 15% of the Atmosphere and it is also where the Ozone layer is located. Last, but not least, is the Troposhpere, which is the closest to the Earth. It ranges from 5 to 11 miles in thickness. All of our weather takes place in this layer and the air tempurature decreases with height.he Exosphere is the outer layer around the Earth. The air is very thin as the air particles are far apart. Beyond the Exosphere, is outer space. The Thermosphere was once called the Ionosphere.
