Without this protective blanket, life on Earth would not exist as it protects us from heat and radiation emitted from the sun and includes the air we breathe.Though oxygen is important for life on Earth, it is not the main part of our atmosphere. According to education website Vision Learning Earths atmosphere is made up of approximately 78 percent nitrogen, 21 percent oxygen, 0.93 percent Argon, 0.04 percent carbon dioxide as well as trace quantities of neon, helium, methane, hydrogen, ozone and krypton, as well as water vapor.But just how high does Earths atmosphere extend? According to NASA the upper layer of Earths environment– the exosphere– extends up to 6,200 miles (10,000 km), above which the atmosphere and space mix. Commercial planes tend to fly in the lower stratosphere so as to avoid the weather systems in the troposphere, according to air travel education website Aero Corner.MesosphereThe mesosphere is the third layer of Earths atmosphere. Exosphere The exosphere is the greatest layer of Earths environment and extends from the top of the thermosphere around 6,200 miles (10,000 km) above Earths surface area according to NASA.
