how is ozone formed in the upper atmosphere state its importance what is responsible for its depletion
Answers
Answer:
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.

Answer:
Explanation: FORMATION Ozone is found naturally in small concentrations in the stratosphere, a layer of Earth's upper atmosphere. In this upper atmosphere, ozone is made when ultraviolet light from the sun splits an oxygen molecule (O2), forming two single oxygen atoms. If a freed atom collides with an oxogen molecule, it becomes ozone.
IMPORTANCE: 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. Ultraviolet (UV) radiation is a known cause of skin cancer, skin ageing, eye damage, and may affect the immune system.
The depletion of ozone layer from the Environment is called ozone depletion. Compounds responsible for depletion of ozone layer: chlorofluorocarbons , hydro-chlorofluorocarbons , methyl bromide, carbon Tetra-chloride, methyl chloroform etc.
