2. Acid rain
Causes
Effects
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.
When acid rain and dry acidic
particles fall to earth, the nitric
and sulfuric acid that make the
particles acidic can land on
statues, buildings, and other
manmade structures, and
damage their surfaces. The
acidic particles corrode metal
and cause paint and stone to
deteriorate more quickly.
