The diagram blow shows how ‘Acid Rain” occurs.
SAMPLE ANSWER
The diagram clearly shows how acid rain is formed. As indicated in the diagram, this process has two types; “Wet deposition’ which refers to acidic rain and snow, and ‘Dry deposition’ is a term used to describe gaseous and particulate matters in atmosphere.
Acid rain occurs by two sources; man-made sources-mainly caused by the release of sulphur and nitrogen compounds during fossil fuel combustion, and natural sources -mainly occurs via natural processes such as volcanoes when sulfurous gases are discharged from erupted volcanoes.
As can be seen, initially, these pollutants are mainly emitted by the heavy industries and environmental factors. These substances can rise very high into the atmosphere, and carried away far from their origins by prevailing winds where they mix and react with water vapour, oxygen, and other chemicals to form more acidic pollutants, known as acid rain or acid deposition. Eventually, water resources, aquatic ecosystems and vegetation are acidified and poisoned.
