HOLE IN THE OZONE LAYER :              SATURDAY,09, April,2011

what is ozone layer:  Ozone(o3) layer is an atmospheric layer arround the earth above the stratosphere it is about 50 km above the Earth.

How it's formed: Ozone layer is formed by the reaction between the Oxygen in the atmosphere and the Ultra Violet Rays from the Sun.

UV Rays -->  O2  -->  O  +  O                                            i       i                                           i       i

O2 + O --> O3

When the UV Rays from the Sun fall on the O2 present in the atmosphere, the  O2 splits in to two  Oxygen atoms. These oxygen atoms again combines with the other O2 molecules present in the atmosphere to form Ozone layer.

Like this O2 molecules present in the atmosphere arround the Earth are converted in to O3 and form the Ozone layer arround the Earth. In the begining Ozone layer first formed on one side of the Earth and then on the other side of the Earth.Like this complete Ozone layer arround the Earth is formed.

Again this ozone splits in to oxygen(O2)molecule and oxygen (O) atom by the UV Rays. These Oxygen (O2) molecules split in to oxygen (O) atoms.and these oxygen (O) atoms then combine with oxygen (O2) molecules to form ozone (O3).like this the chain reaction goes on.

Therefore the process of ozone (O3) layer formation is a chain reaction and this process contineus until oxygen (O2)present in the atmosphere.

THEREFORE THE HOLE IN THE OZONE LAYER MAY NOT BE PRESENT.

BUT AS PER THE STUDIES BY THE SCIENTISTS THERE IS A HOLE IN THE OZONE LAYER. To be contneus ....
