I am the atmosphere. My job is to make sure all living things can survive
I am made up of 5 layers. I am mostly made of nitrogen and oxygen.
I will supply the geosphere with gases, heat, and sunlight. I receive water from the Hydrosphere
If i didn't exist, there would be no oxygen that stays within earth. The planet would lose all living things that depend on oxygen. The planet would constantly change from 250 degrees to -240 degrees from night to day.
