Asteroid Impact Could Destroy Ozone Layer | News | Astrobiology

The model shows that a medium-sized asteroid could affect atmospheric chemistry on our planet, resulting in global ozone depletion. Ozone in Earth’s atmosphere helps protect living organisms from ultraviolet radiation. If ozone levels were depleted for a long period of time, life could face a difficult future.

Ozone layer destruction – Meteorología en Red

Chlorofluorocarbons are chemicals that destroy ozone in the stratosphere through various reactions. It is a gas made up of fluorine, chlorine and carbon. When this chemical reaches the stratosphere, it undergoes a photolysis reaction with ultraviolet radiation from the sun. This causes the molecules to break down and require chlorine atoms.

Do cosmic rays destroy the ozone layer? – Physics World

“These correlations mean that nearly 100% of the ozone loss over Antarctica must be driven by cosmic rays,” he says, pointing out that the degree of variation of cosmic ray intensity and Antarctic ozone are very similar (both about 10%). “In other words, any non-cosmic-ray related mechanism, if it exists, must be a very minor or negligible effect.”

NASA – Ozone Depletion a Bigger Deal Down Under

The ozone is so thin in this part of the world that the weather report on the nightly news includes five-minute sunburn alerts. Ozone is Earth’s natural sunscreen. The ozone layer in the upper atmosphere, or stratosphere, absorbs harmful ultraviolet rays from the sun. In the 1980s, scientists discovered that manmade chemicals destroy ozone to …

NASA – Ozone: What is it, and why do we care about it?

If each chlorine atom released from a CFC molecule destroyed only one ozone molecule, CFCs would pose very little threat to the ozone layer. However, when a chlorine monoxide molecule encounters a free atom of oxygen, the oxygen atom breaks up the chlorine monoxide, stealing the oxygen atom and releasing the chlorine atom back into the stratosphere to destroy more ozone.

Ozone Layer Depletion – Cause, Effects, And Solutions

Ozone layer depletion is the thinning of the ozone layer present in the upper atmosphere. This happens when the chlorine and bromine atoms in the atmosphere come in contact with ozone and destroy the ozone molecules. One chlorine can destroy 100,000 molecules of ozone. It is destroyed more quickly than it is created.
