The ozone layer is the common term for the high concentration of ozone that is found in the stratosphere around 15–30km above the earth’s surface.
It covers the entire planet
and protects life on earth by absorbing harmful ultraviolet-B (UV-B) radiation from the sun.
How does ozone protect the life on Earth?
The ozone layer is a natural layer of gas in the upper atmosphere that protects humans and other living things
from harmful ultraviolet (UV) radiation from the sun
. … The ozone layer filters out most of the sun’s harmful UV radiation and is therefore crucial to life on Earth.
Does ozone protect Earth?
The stratospheric ozone layer is Earth’s “sunscreen” –
protecting living things from too much ultraviolet radiation from the sun
. The emission of ozone depleting substances has been damaging the ozone layer.
How is ozone beneficial to the earth?
Stratospheric ozone is
“good” because it protects living things from ultraviolet radiation from the sun
. … Called stratospheric ozone, good ozone occurs naturally in the upper atmosphere, where it forms a protective layer that shields us from the sun’s harmful ultraviolet rays.
What has depleted the Earth ozone layer?
Ozone depletion, gradual thinning of Earth’s ozone layer in the upper atmosphere caused by the release of
chemical compounds containing gaseous chlorine or bromine from industry and other human
activities. The thinning is most pronounced in the polar regions, especially over Antarctica.
Does UV light destroy ozone?
Ozone residuals are destroyed at UV light wavelengths
ranging from 250 to 260 nm, while microorganism inactivation can be achieved at UV wavelengths ranging from 100 to 400 nm, although a wavelength of 254 nm is most effective.
How do you get rid of ozone?
Your best option might be to keep the windows closed, especially on warm and sunny days with little or no wind.
Running an air purifier
that can remove ozone in your home, either with a carbon filter or using PECO technology, may help lower ozone levels indoors.
Why is ozone bad for you?
How is Ozone Harmful? … 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.
Where is the bad ozone located?
Ozone occurs in two layers of the atmosphere. The
layer closest to the Earth’s surface is the troposphere
. Here, ground- level or “bad” ozone is an air pollutant that is harmful to breathe and it damages crops, trees and other vegetation.
What are the harmful effects of ozone?
Breathing ground-level ozone can trigger a variety of health problems including
chest pain, coughing, throat irritation, and congestion
. It can worsen bronchitis, emphysema, and asthma. Ozone also can reduce lung function and inflame the lining of the lungs.
Why ozone layer is important for human life describe?
The ozone layer is a natural layer of gas in the upper atmosphere which
protects humans and other living things from the harmful ultraviolet (UV) rays of the sun
.
How ozone depletion can be prevented?
How can we protect the ozone layer?
Avoid the consumption of gases dangerous to the ozone layer
, due to their content or manufacturing process. Some of the most dangerous gases are CFCs (chlorofluorocarbons
What are the harmful effects of ozone depletion grade 10?
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.
Which is better ozone or UV?
Best answer:
Ozone
is indeed a much more powerful oxidizer than UV. UV will disinfect the water by killing bacteria and viruses and other living microorganisms (if properly sized with sufficient contact time). … But using ozone increases the risk of creating certain by-products.
Do UV air purifiers produce ozone?
Air purifiers that use ultraviolet light to kill microorganisms (also known as UVGI, ultraviolet germicidal irradiation) only work against certain species. … Therefore, UV-C air purifiers are not ozone-free.
Not only do they produce ozone
, they are not very effective in a residential setting.
Do all UV lights create ozone?
Not all UV lamps result in ozone generation
, however. The key is the glass used in the lamp. Soft glass or regular quartz glass allow the 185 nm UVC to pass through and generate ozone.
