Brownish haze that develops as complex molecules are broken down into ozone and other harmful substances is known as

• A. Snow
• B. Photochemical Smog
• C. Hail
• D. Drizzle

Answer: (B)

Sunlight-driven chemical reactions among air pollutants from vehicle exhaust, especially nitrogen oxides and volatile organic compounds, form ozone and other oxidants. This creates a brownish haze over cities on sunny days. That phenomenon is called photochemical smog. Snow, hail, and drizzle are precipitation types and do not involve the chemical formation of ozone, so they don’t describe this haze.
