Answer:
Ozone is formed when heat and sunlight cause chemical reactions between oxides of nitrogen (NOX ) and Volatile Organic Compounds (VOC), which are also known as Hydrocarbons. This reaction can occur both near the ground and high in the atmosphere.
Ozone is a gas in the atmosphere that protects everything living on the Earth from harmful ultraviolet (UV) rays from the Sun. ... The ozone layer acts as a shield to absorb the UV rays, and keep them from doing damage at the Earth's surface.
The amount of Ozone in the atmosphere began to drop sharply in the 1980s. This decrease is due to the synthetic chemicals like chlorofluorocarbons which are used as refrigerants and in fire extinguishers.
Answer:
UV radiation split some molecular oxygen into free atom,these atom then combine with molecular oxygen to form ozone layer.
The ozone layer act as a protective blanket around the earth which shields the entire earth from harmful ultraviolet radiation that come from the sun .
