What are 5 facts about the ozone layer?
The ozone layer was discovered by Charles Fabry and Henri Buisson, French physicists, in 1913. The ozone layer is able to absorb maximum of 98% of the sun’s UV light. A hole in the ozone layer was discovered in the Antarctic in 1985.
What are three facts about ozone depletion?
Facts About the Ozone Layer
- The word “ozone” means smelly in Greek because the gas has a strong odor.
- CFC molecules are highly stable and can last for up to 100 years.
- One chlorine molecule from a CFC can destroy up to 100,000 ozone molecules.
- Ultraviolet rays can also have bad effects on nature.
What color is the ozone hole?
The ozone layer is a colorless layer of gas. However, it scatters just enough light at the blue end of the spectrum to give the sky its blue color.
How much of the ozone layer is left 2021?
Similar to last year’s season, the ozone hole in 2021 will be one of the largest and longest-living ones on record, coming to a close later than 95% of all tracked ozone holes since 1979.
Why the ozone layer is depleting?
Ozone Depletion. When chlorine and bromine atoms come into contact with ozone in the stratosphere, they destroy ozone molecules. One chlorine atom can destroy over 100,000 ozone molecules before it is removed from the stratosphere. Ozone can be destroyed more quickly than it is naturally created.
What are 3 facts about the exosphere?
10 Facts about Exosphere
- Earth atmosphere is divided into many distinct layers.
- The exosphere is the most outermost layer of earth’s atmosphere.
- This layer start at 500 km above the earth’s surface and goes about 10000 KM.
- The air is extremely thin in exosphere.
Which gas is found in Ozonosphere?
The ozone layer or ozone shield is a region of Earth’s stratosphere that absorbs most of the Sun’s ultraviolet radiation. It contains a high concentration of ozone (O3) in relation to other parts of the atmosphere, although still small in relation to other gases in the stratosphere.
What are the effects of ozone layer depletion?
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.
Who discovered ozone hole?
In 1985 Jonathan Shanklin was a junior researcher at BAS when he discovered a hole in the invisible shield that protects us from solar radiation. We catch up with him to learn about his work and how it has made a difference. It’s 36 years since scientists first discovered the hole in the ozone layer.
Is there still an ozone hole?
Antarctic ozone hole is 13th largest on record and expected to persist into November. The 2021 Antarctic ozone hole reached its maximum area on October 7 and ranks 13th largest since 1979, scientists from NOAA and NASA reported today.
How has ozone depletion changed over time?
Overall, ozone depletion increases with latitude with low levels of depletion at the equator and tropics, and highest depletion at the poles. Although depletion has occurred over both the Antarctic and Artic poles, Antarctica has experienced the most severe development of the ‘ozone hole’.
