pollution produced when acid chemicals are incorporated
into rain, snow, fog or mist. The "acid"
in acid rain comes from sulfur oxides and nitrogen
oxides, products of burning coal and other fuels
and from certain industrial processes. The sulfur
oxides and nitrogen oxides are related to two strong
acids: sulfuric acid and nitric acid. When sulfur
dioxide and nitrogen oxides are released from power
plants and other sources, winds blow them far from
their source. If the acid chemicals in the air are
blown into areas where the weather is wet, the acids
can fall to Earth in the rain, snow, fog or mist.
In areas where the weather is dry, the acid chemicals
may become incorporated into dusts or smokes. Acid
rain can damage the environment. human health and
