ACID Rain
Cause: 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.
Effect: Acid rain makes water sacidic and causes them to absorb the aluminum that makes                    its way from soil into lakes and streams.
Cure: Because nitrogen oxides are created in the process of burning coal and other fossil                      fuels, some power plants are changing the way they burn coal.
GLOBAL Warming Cause: Global warming trend is human expansion of the "greenhouse effect" Warming that                      results when the atmosphere traps heat radiating from Earth toward space. Certain                      gases in the atmosphere block heat from escap…
