Acid rain is rain that is more acidic than in its natural state, and is usually consider to be a pH of less than 5. (Natural rain water is slightly acidic due to the presence of dissolved [[carbon dioxide]].  Acid rain forms when [[sulfur dioxide]] dissolves in [[water]] to make [[sulfurous acid]]. The [[sulfur dioxide]] can also be oxidized to [[sulfur trioxide]] and form [[sulfuric acid]] upon reaction with [[water]]

Acid rain can cause damage to structures and statues, and also plant life.  (For example the [[Black forest]] of [[Germany]] has been heavily damaged by acid rain.)
