Ozone

The ozone is a form of oxygen that has three oxygen atoms in each molecule instead two. It is located inside the stratosphere. Ozone helps in many ways. One way that it helps is that it protects us from u.v rays and keeps air in. But one way that it can be harmful is that it can release harmful gases. Ozone depletion is were there is no more ozone. What could happen if there is no more ozone is that we would not be protected from u.v rays so we would burn up. Also we would have no more air and we would suficate.

Acid Rain

Acid Rain is rain that contains more acid then normal. Some causes are the burning of coal that contains a lot of sulfur oxides substances composed of oxygen and sulfur. Another cause is when nitrogen oxides and sulfur oxides combine with water in the air to form nitric acid and sulfuric acid. A few consequences are one, it can sometimes be strong enough to damage the surface of buildings and statues. Also it harms lakes and ponds. It can make water so acidic that plants, amphibians, fish , and insects can no longer survive in it. Some solutions to this problem are maybe don't burn as much coal. That is acid rain.
