Exosphere: This is the outermost layer of the atmosphere where satellites orbit and the air is extremely thin. An example is how the International Space Station orbits in this region, where particles are so sparse that they can travel long distances without colliding with one another.
Thermosphere: This layer is known for its high temperatures and is where the auroras occur, caused by interactions between solar winds and the atmosphere. An example is the presence of the ionosphere in this layer, which enables radio communications by reflecting radio waves back to Earth.
Mesosphere: This layer is where meteoroids burn up upon entering the atmosphere, preventing them from reaching the Earth's surface. An example is the phenomenon of "shooting stars," which are actually the trails of burning meteoroids in this layer.
Stratosphere: The stratosphere contains the ozone layer, which absorbs and protects us from the sun's harmful ultraviolet radiation. An example is commercial airliners, which typically fly at the lower levels of the stratosphere to avoid weather disturbances occurring in the troposphere below.
Troposphere: This is the layer closest to Earth, where we live, breathe, and experience most of the weather. An example is clouds forming and rain falling in this layer, making it essential for life on our planet.
