1.) what is acid rain and how is it caused?
2.) what is smog? How is it created?

1. Acid rain is caused by a chemical reaction that starts when sulfur dioxide and nitrogen oxides are released into the atmosphere.

2. When sunlight reacts with nitrogen oxides and at least one volatile organic compound in the atmosphere, photochemical smog is formed.

Explanation:

1.) what is acid rain and how is it caused?

Acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. These substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.

Explanation: 2.) what is smog? How is it created?

Photochemical smog is produced when sunlight reacts with nitrogen oxides and at least one volatile organic compound (VOC) in the atmosphere. Nitrogen oxides come from car exhaust, coal power plants, and factory emissions. ... When sunlight hits these chemicals, they form airborne particles and ground-level ozone—or smog.
