What causes ground ozone layer?

Ground-level ozone is formed when pollutants emitted by vehicles, power plants, industrial facilities, and other sources react with sunlight. These pollutants, known as volatile organic compounds (VOCs) and nitrogen oxides (NOx), undergo a chemical reaction in the presence of sunlight to form ground-level ozone. This process is more likely to occur in warm, sunny weather conditions.

Ground-level ozone is formed when sunlight reacts with pollutants such as nitrogen oxides and volatile organic compounds (VOCs). These pollutants are emitted by vehicles, industrial processes, and other sources. When these pollutants react with sunlight, they form ozone, which can accumulate in the lower atmosphere, where it can be harmful to human health and the environment.
