The atmosphere is like a big bubble of transparent air that surrounds earth. there are 4 main layers of the atmosphere

Higher up lies the mesosphere, a very cold layer 50–85 km above Earth where most meteors burn up, and above that is the thermosphere, a very hot layer stretching from about 90–600 km where auroras appear and the International Space Station orbits.
