Acid rain is a severe environmental problem and affects various regions of the world.
Acid rain is a side effect from the burning large amounts of fossil fuels like coal and petroleum, and usually occurs over regions downwind from clusters of large, modern, industrial cities.
Acid rain is an interesting and important environmental phenomenon, particularly considering its impact on natural ecosystems.
When these gases are emitted into the atmosphere, they will react with the water molecules in the air to form acid rain.
The areas affected by acid rain are widespread and these areas may be very far away from the source.
