  • Hi Zarif! how does acid rain usually form?
  • Acid rain usually forms high in the clouds where sulfur dioxide and nitrogen oxides react with water, oxygen, and oxidants.
  • Acid rain is caused mainly by the burning of fossil fuels such as coal and gasoline. Oxides of nitrogen and sulphur are released into the air when fossil fuels are burnt and when they mix with the precipitation in clouds acid rain is formed.
  • Water from the earth's surface evaporates into the atmosphere, where it condenses and precipitates as rain, snow, mist or water vapor and then returns to the surface of the earth.
  • There are several ways to prevent acid rain such as switching to low-sulphur coal; removing the sulphur from the coal before burning; using fluidised-bed combustion processes to burn the coal; and removing the sulphur from the smoke stack after combustion through the installation of pollution control equipment.
  • Acid rain causes acidification of lakes and streams and contributes to the damage of trees at high elevations (for example, red spruce trees above 2,000 feet) and many sensitive forest soils.
  • In addition, acid rain accelerates the decay of building materials and paints, including irreplaceable buildings, statues, and sculptures that are part of our nation's cultural heritage.
