Acid Deposition in AP Environmental Science

Definition

Acid deposition refers to the process by which acidic pollutants, such as sulfuric acid and nitric acid, are deposited onto the Earth's surface through precipitation (rain, snow, fog) or dry deposition (particles settling on surfaces). This can have harmful effects on ecosystems and human health.

Acid Precipitation:

Acid precipitation is a type of acid deposition that specifically refers to acidic substances falling from the atmosphere onto the Earth's surface through rain, snow, or fog.

Nitric Acid: Nitric acid is one of the main components of acid deposition. It forms when nitrogen oxides react with water vapor in the atmosphere and contributes to the acidity of precipitation.

Sulfuric Acid:

Another major component of acid deposition, sulfuric acid forms when sulfur dioxide reacts with oxygen and water vapor in the atmosphere. It is a highly corrosive substance that can cause damage to ecosystems and infrastructure.
