How does the bad ozone destroy the good?
The stratosphere or “good” ozone layer extends upward from about 6 to 30 miles and protects life on Earth from the sun’s harmful ultraviolet (UV) rays. There they are broken down by the intensity of the sun’s UV rays and release chlorine and bromine molecules, which destroy the “good” ozone.
What happens if you breathe in ozone?
When inhaled, ozone can damage the lungs. Relatively low amounts can cause chest pain, coughing, shortness of breath and throat irritation. Ozone may also worsen chronic respiratory diseases such as asthma and compromise the ability of the body to fight respiratory infections.
What does it mean when you smell ozone?
Some people can smell ozone before the storm has even arrived. Before a thunderstorm rolls in, lightning can sometimes rip nitrogen and oxygen molecules in the environment to pieces. This can ultimate result in a small amount of ozone forming, which wind then carries down to ground level.
What is a bad ozone?
Ozone when present in the Earth’s surface is very poisonous gas. Hence called bad. Ozone when present in stratosphere is very protective in nature as it does not allow the harmful ultraviolet radiations to enter the Earth’s atmosphere, hence its called good ozone.
What are the major effects of the ozone hole?
Ozone layer depletion causes increased UV radiation levels at the Earth’s surface, which is damaging to human health. Negative effects include increases in certain types of skin cancers, eye cataracts and immune deficiency disorders.
Is there still a hole in ozone layer?
The 2020 Antarctic ozone hole grew rapidly from mid-August and peaked at around 24.8 million square kilometres on 20 September 2020, spreading over most of the Antarctic continent. There is still enough ozone depleting substances in the atmosphere to cause ozone depletion on an annual basis,” said Dr Tarasova.
What is the current state of the ozone hole?
The 2020 ozone hole grew rapidly from mid-August and peaked at around 24 million square kilometres in early October. It now covers 23 million km2, above average for the last decade and spreading over most of the Antarctic continent.
Why the ozone hole is over Antarctica?
The annually occurring ozone hole over the Antarctic had rapidly grown from mid-August and peaked at around 24 million square kilometres — one of the largest so far — in early October 2020. The expansion of the hole was driven by a strong, stable and cold polar vortex and very cold temperatures in the stratosphere.
What is Chapman theory?
Gouy-Chapman theory (Gouy 1910; Chapman 1913) is an electrostatic model of the spatial distribution of ions adsorbed, but not immobilized, by a charged particle surface reacting with an aqueous electrolyte solution.
What is the Chapman sequence?
A series of reactions, first proposed by Sidney Chapman in the 1930s, to explain the presence of the ozone layer in the earth’s stratosphere. The reaction sequence is as follows: where M is any other molecule in the termolecular reaction.
How big is the hole in the ozone layer above Australia?
The ozone hole in 2020 The first week of September saw the daily ozone hole area increase rapidly by about 10 million km2, reaching a peak of 24.7 million km2 on 20 September. To put this in perspective, that’s an area a bit over three times the size of Australia.
