Most meteors burn up in this layer. Unlike the stratosphere, temperatures once again grow colder as you rise. The coldest temperatures in Earth's atmosphere, about -90° C (-130° F), are found near the top of this layer. The air is far too thin to breathe; air pressure at the bottom of the layer is well below 1% of the pressure at sea level, and continues dropping as you go higher.

The layer humans live in, and nearly all weather occurs in this lowest layer. Most clouds appear here, mainly because 99% of the water vapor in the atmosphere is found here. Air pressure drops, and temperatures get colder, as you climb higher.

Many satellites actually orbit Earth within this layer, including the International Space Station. Variations in the amount of energy coming from the Sun exert a powerful influence on both the height of the top of this layer and the temperature within it. The aurora, the Northern Lights and Southern Lights, occur here. Another name for this layer is the “heat” layer.

The "air" is very, very, very thin, making this layer even more space-like than the thermosphere. In fact, the air is constantly - though very gradually - "leaking" out of Earth's atmosphere into outer space. There is no clear-cut upper boundary. High Earth Orbit satellites can be found here.

The infamous ozone layer is found within this layer. Ozone molecules in this layer absorb high-energy ultraviolet (UV) light from the Sun, converting the UV energy into heat. Unlike the troposphere, the layer actually gets warmer the higher you go! That trend of rising temperatures with altitude means that air in the stratosphere lacks the turbulence and updrafts of the troposphere beneath. Commercial passenger jets fly in the lower part, because this less-turbulent layer provides a smoother ride. The jet stream flows in this layer.
