The Ozone Layer

By Cherakee Ferguson

Where is the ozone layer?

The ozone layer is part of the earths atmosphere and absorbs most of the suns UV rays. It is located in the lower part of the earths stratosphere and is approximately 20 to 30 kilometres away from the earths surface.

What is it made up of?

It has very high concentrations of ozone(o3)and s very small compared to normal oxygen.

It is also made up of 78% nitrogen, 21% oxygen and a bit of argon along wit the ozone which helps make up the atmosphere.

what it does and how does it?

The gasses in the Ozone layers atmosphere, helps block out the suns UV rays, and keeps us from getting sunburnt. The ozone layer does this by breaking down molecules and then absorbing the rays. As the ozone gets thinner from pollution and other things, diseases like cancer, malnutrition and cataracts can occur easier.

What destroys the ozone layer?

Scientists believe that humans are the main cause of the depletion of the ozone layer and that there chemicals that we use in our daily devises such as hairspray and our refrigerators that are released and then destroys the ozone. one of the most common chemicals is called CFC.

Common misconceptions about the ozone layer!

Some people believe the chemical CFC is too heavy to affect the ozone layer and it cant reach it, but, the gasses are not measured in weight and if the wind turbulence is strong enough, it can be carried up to the ozone.

another misconception is that global warming effects the ozone , but it doesn't, it has nothing to do with it.
