ATMOSPHERE GAMES




The earth is surrounded by a layer of gases called the atmosphere. The atmosphere is very important to life on Earth and does many things to help protect life and help life to survive. 

 The atmosphere is made up of mostly nitrogen (78%) and oxygen (21%). There are lots of other gases that are part of the atmosphere, but in much smaller amounts.





Oxygen is needed by animals to breathe and carbon dioxide is used by plant in photosynthesis.
