====O 2 is oxygen gas. At standard temperature and pressure, two atoms bond to form dioxygen, a colorless, odorless, and tasteless diatomic gas. This substance is necessary to substain most terrestrial life.Trioxygen (O 3 ), usually known as ozone, is a very reactive allotrope that is very harmful to the lung. Ozone is produced on the upper atmosphere.The ozone layer of the atmosphere functions as a protective shield for the planet. - Alejandro====

====The ozone layer was discovered in 1913 by the French physists Charles Fabry and Henri Buisson. The ozone layer absorbs 97-99% of the sun's ultraviolet light, which damages a lot of Earth's life forms. Ozone in the Earth's stratosphere is created by ultraviolet striking oxygen molecules containing two oxygen atoms(O2), splitting them into individual atoms; the atomic oxygen then combines with unbroken atoms of oxygen, forming ozone (O3).==== -Alejandro ====The Ozone Layer is used to protect Earth from Meteor Showers, and other things that could possibly damage the world.However, there is a hole in the Ozone Layer.The hole is right over Australia meaning that Australia is unprotected by meteorites and other things. There is no way to fix it. But sometimes, Meteors can get past it and so they hit Earth. Only occansionally does this happen. Therefore, it is important for Earth to have the Ozone Layer; to protect us.==== -Kahlila

However, if you notice the hole in the middle that is the hole in the Ozone which is not protected.
-Kahlila Overall, chemical reactions are important to everyday life because they are the things that keep everything moving. Our bodies, minds, and everything around us have chemical reactions going on all the time. It is important for chemical reactions to be around because without them, we wouldnt be able to breathe, eat, drink, or live in general. -Kahlila
