Acid rain occurs in multiple locations across the planet.


Acid rain, or rain with a lower pH due to nitric and/or sulfuric acids, falls in many places across the globe. Natural rain is typically somewhat acidic, with a pH just below 6. Acid rain usually has a pH of 5.5-5.0 but can be lower in some areas.

Because of how acid rain is formed, it is often found near areas where lots of fossil fuels are burned and/or areas that lack strict emissions regulations.
