Earths Atmosphere

Earths atmosphere is very different from the moon and planets with no atmospheres for many reasons.Earths atmosphere makes conditions on earth suitable for living things.This is why we could not live on any other planet that we know of.Earths atmosphere is made up of nitrogen,oxygen,carbon dioxide,water vapor,and many other gases,as well as particles of liquids and solids.Oxygen is the second most abundant gas in earths atmosphere following nitrogen and is the reason we can breath on earth.The atmosphere keeps most of the earths surface warm by trapping energy from the sun.It also protects living things from dangerous radiation from the sun.Earths atmosphere also protects the earth from being hit by most meteoroids and rocks from outer space.
