The ozone layer protects life on earth by absorbing harmful ultraviolet radiation . As the layer thins, the upper atmosphere grows colder, causing winds in the stratosphere and in the troposphere below to shift, displacing jet streams and storm tracks.
What are the advantages and disadvantages of ozone layer?
Advantage and Disadvantages :Ozone occurs in 2 layers of the atmosphere. 1. Disadvantage : In troposphere layer bad ozone is present which act as an air pollutant which is very harmful to breathe and also it damages the crops in field and other vegetation.
What is the importance of ozone layer Class 10?
The importance of ozone is defined by the fact that it protects the earth from harmful ultraviolet rays from the sun . The ozone layer is found in the upper regions of the stratosphere where it protects the earth from the harmful ultraviolet rays of the sun. These radiations can cause skin cancer in humans.
What is ozone layer and its effects?
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.
What is the advantage of having ozone layer?
Why is Ozone Layer important? Ozone protects the Earth from harmful ultraviolet (UV) rays from the Sun . Without the Ozone layer in the atmosphere, life on Earth would be very difficult. Plants cannot live and grow in heavy ultraviolet radiation, nor can the planktons that serve as food for most of the ocean life.
How we can protect ozone layer?
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), halogenated hydrocarbon, methyl bromide and nitrous oxide. Minimize the use of cars.
How does ozone hurt?
Ozone can cause the muscles in the airways to constrict , trapping air in the alveoli. This leads to wheezing and shortness of breath. Depending on the level of exposure, ozone can: Cause coughing and sore or scratchy throat.
What is harmful for ozone layer?
Ozone depleting substances are chemicals that destroy the earth’s protective ozone layer. They include: chlorofluorocarbons (CFCs) halon .
Is ozone stronger than bleach?
One of the most powerful disinfectants is ozone. In fact, when compared to the most popular disinfectant chlorine bleach, the effects of ozone sanitation are 1000 times stronger than chlorine bleach and kills any and all bacteria and viruses within 2 seconds!
What is the most important function of ozone?
a) The Ozone layer at the upper atmosphere perform the function of absorbing the harmful ultraviolet (UV) rays which are coming from the sun and prevents them from reaching the earth. These UV rays cause harmful effects to humans, even to animals and plants also.
What is the importance of ozone day?
World Ozone Day is observed on September 16 every year to spread awareness among people about the depletion of Ozone Layer and find possible solutions to preserve it . On this day, people from all over the world hold talks and seminars on the ozone layer.
What is ozone layer short answer?
What is the ozone layer? 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 do humans affect ozone layer?
Human activities cause ozone depletion and global warming
Ozone depletion occurs when chlorofluorocarbons (CFCs) and halons —gases formerly found in aerosol spray cans and refrigerants—are released into the atmosphere (see details below).
What will happen if ozone layer is destroyed?
radiation. A diminished ozone layer allows more UV radiation to reach the Earth’s surface . For people, overexposure to UV rays can lead to skin cancer, cataracts, and weakened immune systems. Increased UV can also lead to reduced crop yield and disruptions in the marine food chain.
What are the main causes of ozone depletion?
The main cause of ozone depletion and the ozone hole is manufactured chemicals , especially manufactured halocarbon refrigerants, solvents, propellants, and foam- blowing agents (chlorofluorocarbons (CFCs), HCFCs, halons).
How is ozone harmful to us?
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.
