Hemrietta(aged 16):The biggest problem with the environment is the ozone layer(臭氧层); there's a hole,and it's getting bigger.It's made by cars and aeroplanes-things give off fumes.There should be law that you are
The ozone layer of the atmosphere protects Earth from harmful solar radiation. However, the atmosphere is fragile, and evidence indicates that it has thinned. In 1989, the Montreal Protocol was put into effect to counter human damage to the ozone layer, and there have been signs of progress ...
Why are there ozone holes in the stratosphere? Why is the stratospheric ozone layer important for human health? How are humans damaging the ozone layer? Why does ground-level ozone form when its warm? Is the ozone layer good or bad?
The good news, according to a new report about ozone depletion, is that the ozone layer will recover in 50 years—if parties to the 1987 Montreal Protocol on Substances that Deplete the Ozone Layer fully adhere to the treaty, and if other conditions that could affect the atmosphere remain ...
Although some fluctuations in measurements are normal, Newman notes that the hole closing is all thanks to human-produced changes. “The Montreal Protocol has not only saved the ozone layer but is also one of the most effective climate agreements we have in place right now,” he says. ...
But now air pollution is destroying it and that has made a very big hole in the ozone layer(臭氧层).3. B This is very dangerous because it can cause cancer.Carbon dioxide( $$ C O _ { 2 } $$) in the air has increased a lot. 4. G It has formed a“blanket(毛毯)” around ...
The earth's ozone layer(臭氧层) is slowly but clearly healing(愈合), a new United Nations report said.So, what is the Ozone layer? Why is it so important to us? As a layer of ozone high above the earth's surface, it protects living things on the earth. It stops harmful radiation(...
While the healing of the ozone layer has taken longer than initially expected when scientists first raised the alarm about the ability of long-lived chemicals, known as chlorofluorocarbons or CFCs, to deplete the protective ozone layer, the new findings offer a rare instance of positive environmenta...
(i) Why is the thin ozone layer on top of the stratosphere crucial for human survival ? Identify to which part of electromagnetic spectrum does this radiation belong and write one important application of the radiation. View Solution Rakesh and Rajesh are 8th class students. They are fond of ...
Discuss the depletion of our ozone layer. Why we should care, what is causing it and what can we do to stop it? Discuss the molecule ozone and its role as being both beneficial and harmful to our health. Explain the differences between "good...
