Question

Where is the "ozone layer" located? How and why is stratospheric ozone beneficial for people, whereas tropospheric ozone is harmful? How do chlorofluorocarbons (CFCs) deplete stratospheric ozone? Why is this depletion considered a long-term international problem? What has been done to address this problem?

Answer 1

Answer:

The ozone layer is usually referred to as a blanket that protects the earth from the harmful incoming solar radiation. It is located in the Stratosphere layer but also there is another ozone layer in the troposphere, commonly known as the troposphere ozone.

The stratospheric ozone is considered to be good ozone because it is located at a high altitude and it directly acts as a shield protecting the earth from the solar radiation, which can cause various types of skin diseases and also can increase the surface temperature of the earth.

On the other hand, the troposphere ozone is considered to be bad as it is located near to the ground surface and is mainly comprised of the greenhouse gases, that are harmful to the atmosphere and also increases the surface temperature of the earth.

CFC is one of the greenhouse gases that are harmful to the atmosphere because CFC molecules are continuously hit by the solar radiations that breaks the bond between the carbon and chlorine, resulting in the production of a single Chlorine atom, which eventually breaks down down the ozone layer by reacting with it. This is how the CFCs depletes the stratospheric ozone.

The depletion of the ozone layer leads to the global climatic changing, affecting all the biotic and abiotic components of the earth. This is a long term effect. This global warming is a threat to destroy the earth, so preventive measures must be taken in order to reduce the causes and use of those substances that can lead to catastrophic changes.

Answer 2

Answer:

Stratosphere, helps block UV rays,

Explanation:

• The ozone is located in the stratospheric zone of the troposphere and is found at an altitude of about the 17 to 30 km and is it acts as a filter to block the harmful effects of the solar radiation.

• It is harmful as it reacts with the natural gases and causes the greenhouse effects that is contributed to the human pollution and has respiratory problems. The CFC is also in important constituents that destroy the formation of the ozone a is directly related to the environmental problems and it felt over the time and human and the plats are both vulnerable to the sun's harmful UV rays.

• The various countries have made several attempts to stop this and have banned the use of the greenhouse gases and CFC and thus IPCC is also trying to make countries ratify the environmental norms and the standards.
