Earth's atmosphere is the only in the solar system that keeps harmful radiation from the sun off the planet, and can hold in oxygen enough to support life how we know it.
As you can see in this photo the atmosphere has difrent layers, and appers darker as you get higher up.(the reason the sky is blue is due to the sun light shining through the gases in it makes it appear this color. acculy it is clear, so sky would be black like space.)
It is made up of 78% Nitrogen, 21% Oxygen, .5% Argon gas, and .5% Carbon Dioxide.
Protects planet from the Sun's radiation and keeps oxygen and water inside to support life.
It burns up incoming objects (ussaly before they make contact with the surface)
