Why do we care about ozone layer?

Why do we care about atmospheric ozone? Ozone in the stratosphere absorbs some of the Sun’s biologically harmful ultraviolet radiation. … The ozone that occurs naturally near the surface and in the lower atmosphere is also beneficial because ozone helps remove pollutants from the atmosphere.

Why is it important to protect 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 is ozone prepared Class 12?

Ozone is prepared by passing silent electric discharge through pure, cold and dry oxygen in a specially designed apparatus called ozoniser. The formation of ozone from oxygen is an endothermic reaction.

Why is ozone Day on 16th September?

In 1994, the General Assembly proclaimed 16 September as the International Day for the Preservation of the Ozone Layer, commemorating the date in 1987 on which the Montreal Protocol on Substances that Deplete the Ozone Layer was signed.

What is ozone hole Class 10?

The increase in heat and depletion of ozone around the Earth’s Polar Regions is called the ozone hole. … As the ozone molecules are broken down they are now unable to absorb the UV radiations and we experience the intense UV radiation on the earth surface.

How do we celebrate Ozone Day?

World Ozone Day is observed on September 16, every year. It is celebrated to spread awareness among people about the depletion of the Ozone Layer and search for possible solutions to preserve it. On this day, people from all over the world are expected to join the Montreal protocol to join the talks and seminars.

How does ozone form naturally?

Stratospheric ozone is formed naturally through the interaction of solar ultraviolet (UV) radiation with molecular oxygen (O2). The “ozone layer,” approximately 6 through 30 miles above the Earth’s surface, reduces the amount of harmful UV radiation reaching the Earth’s surface.

How does ozone layer protect us from harmful effects in the environment?

The ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (UVR) from the sun, protecting life on Earth from its potentially harmful effects. … That is,the lower the ozone levels, the higher the solar UVR.

How do you make O3?

Preparation of ozone

Ozone is prepared in laboratory by passing silent electric discharge through dry oxygen. By passing the electric current some of the oxygen molecules dissociate and then atomic oxygen combines with oxygen molecules to form ozone.

What is silent electric discharge?

Silent electric discharge is a current running at high voltage which makes no sound and is used to stabilize the molecules of ozone prepared as Ozone is initially unstable because: O2+O->O3.

What is dry oxygen?

A dry Oxygen is obtained by passing the Oxygen gas over a tower containing drying agents like phosphorus pentoxide. , fused calcium chloride. or bubbling gas through sulphuric acid. . Dry Oxygen is used in the oxygen delivery system for patients.

What is the Colour of ozone?

It is a pale blue gas and consists of three oxygen atoms. Formed in the ozone layer of the stratosphere, it is harmful to life. Ozone, O3, is an allotrope of oxygen. Ozone has pungent an odor, and its color is blue- black in its solid and liquid form.

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.

Who started Ozone Day?

World Ozone Day: History

The United Nations General Assembly, in 1994, declared 16 September as the International Day for the Preservation of the Ozone Layer/ World Ozone Day. This day marks the signing of Montreal Protocol on Substances that deplete the Ozone Layer, in 1987.

When was the first ozone hole discovered?

May 16, 1985
In the scientific journal Nature on May 16, 1985, three scientists from the British Antarctic Survey announce their detection of abnormally low levels of ozone over the South Pole.

What are 3 causes of depletion to the ozone layer?

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).

Which gas is destroying the ozone layer?

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.

How many years has the ozone layer been protected?

35 years
In 2020, the theme for World Ozone Day is “Ozone for life: 35 years of ozone layer protection,” signaling that “not only is ozone crucial for life on Earth, but that we must continue to protect the ozone layer for future generations,” according to according to the United Nations Environment Programme (UNEP) website.

What is the theme of ozone 2021?

The theme for 2021: The theme for 2021 for International Day for the Preservation of the Ozone Layer is ‘Montreal Protocol -‘Keeping us, our food and vaccines cool.

What is the theme for Ozone Day 2020?

The theme of World Ozone Day 2020 was ‘Ozone for life: 35 years of ozone layer protection‘. It marks 35 years of the Vienna Convention and 35 years of global ozone layer protection. This stratospheric layer shields Earth from most of the sun’s harmful ultraviolet radiation.

Is ozone a greenhouse gas?

Ozone is technically a greenhouse gas, but ozone is helpful or harmful depending on where it is found in the earth’s atmosphere. … There are human-made industrial chemicals that break down ozone in the stratosphere and create holes in the ozone layer.

How much ozone is in the air we breathe?

The ozone health standard is an 8-hour average concentration of 70 parts per billion (ppb). NPS ozone health advisories are based on the EPA air quality index levels shown below.

What is ozone smell?

Some people think that ozone is the scent that fills the air right after heavy rain or a thunderstorm. The smell of ozone reminds some of the chlorine, metal, burnt wire. Most people can detect approximately 0.01 mol of ozone in the air, thanks to its rather pungent odor.

Which helps protect the Earth from radiation?

Ozone in the stratosphere protects life on Earth from harmful ultraviolet (UV) radiation and is therefore often called ‘good’ ozone. This in contrast to ozone in the troposphere, the lowest layer of the atmosphere, where it is an air pollutant and can be harmful to humans, animals and vegetation.

How does ozone layer protect us from UV rays Brainly?

Answer: The stratospheric ozone layer absorbs ultraviolet (UV) radiation, preventing dangerous UV rays from hitting Earth’s surface and harming living organisms. UV rays cannot be seen or felt, but they are very powerful and change the chemical structure of molecules.
