pollution

Pollution is a very bad thing that makes the ozone layer get smaller. the type of pollution i am learning about is photochemical smog. This smog occurs when there is burning oil and burning coal. That is just two of them, whats in photochemical smog is Acid Rain which could cause Asthma, bronchitis, coughing and chest pain, some people try to stop all of the pollution by inventing new things.

Our Earths Atmosphere

Our Earths atmosphere is a life giving blanket, its made up of nitrogen, oxygen, carbon dioxide, water vapors, and many others. Our Atmosphere is so important because it provides us all kinds of stuff, if we didn't have the Atmosphere then the earth would practically be dead and would look like mars. the Atmosphere is made up of 78% of nitrogen, 21% of oxygen, and 1% other. The Atmosphere has an ozone layer, and what this does is keep out all of the ultra violet rays. One problem about the Ozone layer is that it has a hole that is growing bigger. There are four layers of the Atmosphere. In one layer theres is solids and liquids, in the other theres were our planes fly and theres even a part were theres nothing. In conclusion that is my essay.
