why does life on earth require the presence of the ozone layer?

Answer 1

I'm back!

The atmosphere protects life on Earth. It is an invisible shield. It allows percipitation and snow. IT also allows dust particles to be picked up by wind. All very important to the way Earth has become what it is.

What about the Ozone layer? In the history of Earth, millions of years ago a surplus amount of oxygen was somehow present suddenly. This extra amount of Oxygen produced an extra layer in the atmosphere called the ozone layer.

This has made it so easy for life to exist becuase it protects us from Ultraviolet Radiation. Also, it deflects even more sun rays back into space (very good).

In the last Q, i mentioned about how the balance is off between Oxygen and Carbondioxide. Well, hopefully that made it clearer because the Ozone layer is made of Oxygen and O2 dissolves VERY easy when something like Carbondioxide is present.

Answer 2

The radiation from the sun would kill u. A more correct name to the ozone layer is Van Allan Belt.
