Atmospere of earth
The atmosphere of Earth is a mix of nitrogen, oxegon and a lot of other gases that surround the Earth. The atmosphere is made of 5 layers. The first layer is of weather and clouds, called the troposphere layer. The second is so stable that most jet aircrafts fly there, called the stratosphere layer. The third is of burnt metoers and rock objects, called the mesosphere layer. The fourth can rise up to 1,500 degrees Celsius or higher, called the thermosphere. The fifth and final layer reflects radio waves back to the Earth, called the Ionosphere layer. There is also one very thin layer called the exosphere layer that is made of atoms and molecules. The Earth's atmosphere is what makes the Earth livable by blocking some dagerous rays of the sun and meteoriods/astroids/flying objects in space. Thats why if we didn't have the atmosphere we would not be living.
