The layers of the atmosphere
There are technically only four layers of the atmosphere, but there is also the exosphere.This includes the troposphere,this is the layer you live in. Weather occurs here and planes fly here,most of our oxygen and gasses are in this section.The next layer is the stratosphere this where most jets fly,this is because it is the most stable.This is also where the ozone layer is.It keeps the suns harmful rays contained.
Then there is the mesosphere it has the coldest temperature.lastly the thermosphere it is where space shuttles are.The exosphere is outer space and the hottest of all atmospheres.
