Acid Deposition

Acid Rain

Acid deposition is a term that includes all processes by which acidic components as precipitates or gases leave the atmosphere. There are two main types of acid deposition: Wet acid deposition: rain, snow, sleet, hail, fog, mist, dew fall to the ground as aqueous precipitates. Dry acid deposition: acidifying particles, gases fall to the ground as dust and smoke, and later dissolve in water to form acids. Acid Deposition
