Question

Acid rain is formed when pollutants like sulfur dioxide ( SO2
) are released into the atmosphere. These pollutants react with gases to produce strong acids. Which of the following is one source of the pollutants?
vehicles emissions
spraying chemicals inside
extremely thick fog
contaminated water

Answer 1

One source of the pollutants that contribute to acid rain, such as sulfur dioxide (SO2), is **vehicles emissions**. Vehicle emissions, particularly from fossil fuel combustion, release a variety of pollutants including sulfur oxides and nitrogen oxides, which can react in the atmosphere to form acids that lead to acid rain.
