OZONE LAYER DESTRUCTION

Joson Anjo C. CasillanVIII-Nelson Mandela

What is Ozone layer The ozone layer forms a thin shield high up in the sky. It protects life on

Earth from the sun's ultraviolet (UV) rays. The ozone layer is a belt of naturally occurring ozone gas that sits 9.3 to

18.6 miles (15 to 30 kilometers) above Earth and serves as a shield from the harmful ultraviolet  radiation emitted by the sun.

If it’s too much ozone, the earth will be frozen or freeze because no sunlight can pass through

Ozone layer does it change in a regular way

How does it form and what is it made of ?

It forms from 2 oxygen that breaks down one and forms at the oxide turning to O3

It’s made of 3 Oxygen and also known as “Ozone” Smog (NOx) and volatile organic compounds (VOC) can react to sunlight

and can create ozone

What destroys Ozone There are one compound that can destroy the ozone and known as

chlorofluorocarbon (CFC) When the UV ray breaks the chlorine, the chlorine will attach to the

ozone molecules to oxygen molecule, and when the chlorine monoxide is attached to singular oxygen, the chlorine is free and breaks as many as they can.

Aerosols are the spray cans that damages the ozone

Ozone hole There is an ozone hole that remains at south pole and north pole Because they are not affecting the sunlight and they have special

atmospheric and stratospheric clouds (meaning low latitude of clouds)

How Ozone blocks UV ray ozone blocks almost all of UV ray and has chance to reach at the ground Clouds blocked UV ray half of them and the ground reflected 10% of UV

ray absorbs most of the Sun's ultraviolet (UV) radiation. The ozone layer absorbs 97–99% of the Sun's medium-frequency

ultraviolet light.
