Located in the stratosphere, the ozone layer blocks potentially harmful ultraviolet energy from reaching our planet's surface without it, humans and animals could experience increased rates of skin cancer and other ailments. The ozone layer is a belt of the naturally occurring gas ozone it sits 93 to 186 miles (15 to 30 kilometers) above earth, and serves as a shield from the harmful ultraviolet b (uvb) radiation. The ozone layer in the stratosphere is thin but powerful however, because it occurs in such a low concentration, it's vulnerable to ozone-depleting chemicals, such as cfcs cfcs are compounds that react with ozone in the presence of uv light by splitting the three oxygen atoms into one o 2 molecule and one clo molecule the clo molecule may react with a single oxygen atom, creating more atmospheric oxygen and a single chlorine atom, which is then free to start the cycle anew. Earth’s ozone layer protects the planet’s surface from some of the sun’s more harmful rays that can cause cancer and cataracts in humans, and damage plant life, according to nasa in the mid-1980s, researchers identified a massive hole in the ozone layer over antarctica and determined that it had been caused largely by human-produced chemicals called chlorofluorocarbons (cfcs.
The ozone layer or ozone shield is a region of earth's stratosphere that absorbs most of the sun's announced that the global depletion of the ozone layer may be slowing down because of the international regulation of ozone-depleting substances in a study organized by the american new directions in safeguarding the planet. Ozone layer keeps getting bigger and bigger each year since the late 1970s, much of the protec-tive layer of stratospheric ozone above antarctica has disappeared during september, creating what is popu-larly known as the ozone hole the antarctic hole now measures about 9 million square miles, nearly the size of north america.
Ozone layer depletion is one of the most serious problems faced by our planet earth it is also one of the prime reasons which are leading to global warming ozone is a colourless gas which is found in the stratosphere of our upper atmosphere.
A study found that despite humanity's concerted efforts over the past 30 years, the ozone layer keeps thinning over the planet's most populous areas the ozone layer is not recovering and we. “we decided collectively, as a world, ‘let’s get rid of these molecules’ we got rid of them and now we’re seeing the planet respond” sharp reductions in cfcs spell a promising future for the planet most research into the ozone layer takes places in october, when seasonal changes mean that the hole is at its peak. The ozone layer is important because it filters harmful ultraviolet radiation as it travels from the sun to the surface of the earth these ultraviolet rays can harm both plant and animal life after observation of a depletion of the ozone layer from the addition of chlorofluorocarbons and other man. There's more evidence that the hole in the ozone layer over antarctica is recovering and that humans' efforts are making a difference at the same time, however, a 2018 study suggests the ozone layer is surprisingly thin at lower latitudes, where solar radiation is stronger and billions of humans live.
The royal netherlands meteorological institute (knmi) is using instruments on several satellites to follow the evolution of ozone around the planet the gas comes in two flavours on the one hand, at an altitude of 20-30 kilometres, natural ozone provides a protective layer, absorbing the sun's harmful ultra-violet radiation. The atmosphere is a layer of air that protects our earth from harmful uv radiation it is also a layer of gases which traps and maintains heat so that life can exist on earth composed mostly of nitrogen and oxygen, the atmosphere is made of four distinct layers. Although the ozone layer has rebounded around the poles, scientists are worried that it's still shrinking in the middle latitudes of the planet.
The ozone layer that protects us from harmful ultraviolet radiation continues to thin over populated areas of the world, a new study warns scientists say the layer is in better shape, however, over the north and south poles ozone has been declining globally since the 1980s.
