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.

Ozone molecules, which are simply made of three joined oxygen atoms, are always being destroyed and reformed naturally. But CFCs in the air make it very difficult for ozone to reform once it’s broken apart. The ozone layer, which only makes up percent of Earth’s atmosphere, is getting thinner and thinner all the time. “Ozone holes” are popular names for areas of damage to the ...

Scientists have already seen the first definitive proof of ozone recovery, observing a 20 percent decrease in ozone depletion during the winter months from 2005 to 2016. In 2019, abnormal weather patterns in the upper atmosphere over Antarctica dramatically limited ozone depletion, leading to the smallest hole since 1982. Models predict that the Antarctic ozone layer will mostly recover by 2040.

Human activity is the major factor in tipping that natural balance, mostly from releasing artificial chemicals, known as ozonedepleting ...

How is ozone formed in the upper atmosphere?

+

20200529· Ozone is formed as ultraviolet radition from the sun breaks down oxygen in the atmosphere, O2, into atomic oxygen with a single atom. The excited free oxygen atom can bond with O2 to form ozone. Sunlight in the upper atmosphere can easily split ozone into an oxygen atom and an oxygen molecule.
