Understanding Acid Rain and Ecosystem Health Quiz

Acid rain is caused by the emission of sulfur dioxide and nitrogen oxides into the atmosphere.

The sulfuric and nitric acids formed in the atmosphere fall to the ground as wet or dry deposition.

Acid rain can be measured using the National Atmospheric Deposition Program's National Trends Network.

Dry deposition is difficult and expensive to measure, while wet deposition is measured by the NADP/NTN.

The Long-Term Monitoring (LTM) Network measures and monitors surface water chemistry at over 280 sites to provide valuable information on aquatic ecosystem health and how water bodies respond to changes in acid-causing emissions and acid deposition.

The LTM Network is a valuable resource for understanding how acid deposition affects aquatic ecosystems and how they respond to changes in emissions and deposition.
