Acid rain is a term that describes acid that essentially falls out of the atmosphere.
Wet acid rain, which is also called wet deposition, refers to acidic rain, fog and snow. As this flows throughout the ground, it can affect plants and animals. Dry acid rain refers to gasses and particles. Wind blows these acidic particles and gasses onto buildings, cars and trees and they can also be washed from trees and other surfaces. According to the Environmental Protection Agency, scientists believe that sulfur dioxide and nitrogen oxides are the primary cause of acid rain.
