Ozone Holes: Scientists are discover 7 times larger ozone hole over the Tropics

Ozone Holes: Scientists are  discover 7 times larger ozone hole over the Tropics 

Ozone Hole 2022: The scientists at the Canada's Waterloo University have been  discovered a large ozone hole in the lower stratosphere, which is a  seven times to larger than the one over Antarctica. The new ozone hole was a  discovered over the tropics and has been reportedly been there for over a  30 years.

The large ozone hole in the lower stratosphere over the tropics is the comparable in  a depth to that of the Antarctic hole but it is  a roughly seven times  are larger in  a area.

The discovery was made by the Qing-Bin Lu, a scientist from the University of the  Waterloo in a Ontario, Canada. The study was published in the journal AIP  are Advances.

What is an ozone layer?

The Ozone layer is a gas layer in the Earth's  are stratosphere that envelops are  the planet and the  protects it from the Sun's harmful to the ultraviolet rays. The layer contains a high concentration of the  ozone (O3) in a  relation to the  other parts of the atmosphere.

Where is ozone layer?

The ozone layer is a generally found in the lower portion of the stratosphere, about a  15-35 kilometers (9 to 22 mi) above a  Earth. Its thickness varies seasonally and the geographically. The ozone layer absorbs a 97 to 99 percent of the Sun's medium-frequency ultraviolet light, which could be otherwise potentially damage exposed life a  forms near the surface.

What is ozone hole?

The ozone hole is an a area where with  the exceptionally depleted levels of the gas. The ozone hole also  are refers to  the thinning of the protective ozone layer. The loss of the gas in an a ozone hole is 25 per cent more than the undisturbed atmosphere.

Where is ozone hole?

So far, scientists were  the warning of an ozone hole that forms above  the Antarctica every September. The 2021 Antarctic ozone hole had been  reached its maximum area on a October 7 and it is ranked as the 13th largest since a 1979.

The new ozone hole discovery is a  above the tropics, the area between the tropic of the  Cancer and the tropic of  the Capricorn.

What causes ozone holes

Human activities are the main cause of  the depletion of the ozone gas through uses of the  gases like a chlorofluorocarbons (CFCs). These chemicals are  escape into the atmosphere through refrigerants, propellant devices, spray cans and the other such things and  the release chlorine after coming into the  contact with the ultraviolet rays of the Sun, which ultimately break down  on ozone molecules in the upper the atmosphere.

Why is ozone hole harmful?

The formation of the ozone hole is a cause of  a great global concern, as the depletion of the ozone layer can be lead to increased ground-level  in UV radiation. The increased radiation can be  increase risk of  the skin cancer and  the cataracts in humans.
