What are the layers of the atmosphere separated by?
Consequently, what separates the layers of the atmosphere?
The tropopause is at the top of the troposphere and separates it from the stratosphere. As air rises through the troposphere it cools due to reduced air pressure (Gay-Lussac's law). Incidentally, the reason we see the warming in the stratosphere is because this is the point of the atmosphere where the ozone layer is.
Beside above, how many layers are in the atmosphere? five
Keeping this in consideration, what causes the layers of the atmosphere?
We call this region of atmosphere the ionosphere. The main source of these layers is the Sun's ultraviolet light which ionizes atoms and molecules in the Earth's upper atmosphere. During this process, electrons are knocked free from molecules or particles in the atmosphere.
Which layer is the hottest layer of the atmosphere?
