Answer:
The atmosphere is a mixture of gases that surrounds the planet. On Earth, the atmosphere helps make life possible. Besides providing us with something to breathe, it shields us from most of the harmful ultraviolet (UV) radiation coming from the Sun, warms the surface of our planet by about 33° C (59° F) via the greenhouse effect, and largely prevents extreme differences between daytime and nighttime temperatures. The other planets in our solar system also have an atmosphere, but none of them have the same ratio of gases and layered structure as Earth's atmosphere.
