Acid Rain - University of Wisconsin–Madison

Like wet deposition, the occurrence of “dry deposition” of acids varies in different areas, depending on distance from the emission source and climatic conditions. What Causes Acid Rain? Acid rain is linked to both natural and man-made sources. Nitrogen oxides are formed through the extreme heating of air when a thunderstorm produces lightning.

Acid rain - Wikipedia

Acid rain is a rain or any other form of precipitation that is unusually acidic, meaning that it has elevated levels of hydrogen ions (low pH).It can have harmful effects on plants, aquatic animals and infrastructure.
