Atmospheric Structure and Ozone

Chlorofluorocarbons (CFCs) are well-known ozone-depleting substances that release chlorine atoms when exposed to UV radiation, which then destroy ozone molecules.

Ozone gets converted into oxygen due to the action of CFCs in the environment and results in the depletion of the protective ozone layer of Earth.

This layer of atmosphere has ozone layer and is present next to troposphere.

The ozone layer in the stratosphere absorbs the majority of the Sun's harmful ultraviolet (UV) radiation, protecting life on Earth.

The stratosphere contains the ozone layer, which absorbs the majority of the ultraviolet radiation from the Sun. It is located above the troposphere.

Ozone is an inorganic molecule with the chemical formula O3. It consists of three oxygen atoms bonded together.

The ionosphere contains a high concentration of ions and free electrons, which allows it to reflect radio waves back to Earth, facilitating long-distance communication.

The ozone layer in the stratosphere absorbs the majority of the sun's harmful ultraviolet radiation, protecting life on Earth.

Water vapours and certain gases in the atmosphere absorb infrared radiations, causing what is called the greenhouse effect. These infrared radiations come from materials on the earth's surface that have been heated by sunlight. These absorbed infrared radiations heat up the atmosphere. 

This is the correct option as this is not a factor that is responsible for life on Earth. It is the distance of the Earth from the Sun that is a factor responsible for life on Earth. This distance is sufficient to keep the temperature on the surface of Earth at an average of 30 degree C.

Ozone layer is a sub layer of Stratosphere. It is in the lower stratosphere, from 6 to 25 miles above the ground. There is also ozone present in the lower troposphere, but the ozone layer in the stratosphere contains helpful ozone that blocks much of the Sun's ultraviolet radiation. Without this layer, life on earth would be very difficult. 

CFC causes ozone holes in the ozone layer. The hole in the ozone layer happens because the ozone in the stratosphere is destroyed by chlorine and bromine from halogen atoms. These atoms come from man-made halocarbon refrigerator gases i.e. chlorofluorocarbons or CFCs which are emitted at ground level but move up into the ozone layer.
