7.7 Acid Rain

acid rain and deposition is due to what

nitrogen oxides and sulfur oxides from anthropogenic and natural sources in atm.

nitric oxides that comes from motor vehicles and (and sulfur dioxides) coal burning power plants cause what

acid deposition

what type of community does acid deposition mainly affect?

communities that are downwind from coal burning power plants

acid rain and deposition can lead to ___ of ____ and _____

1. acidification of

2. soils and bodies of water

3. corrosion of human made structures

what affects the impact that acid deposition has on region

regional difference in soil and bedrock

what can limestone bedrock do

neutralize effect of acid rain on lakes and ponds

acid rain occurs from..

when sulfur dioxide and nitrogen oxide reacts with water, oxygen, and other chemicals in atm. to form sulfuric and nitric acids

what happens when acidic water flows through soil

aluminum (toxic to plants) in clay is mobilized and nutrients and minerals are transported into waterways

e.g. - trees are affected (cant photosynthesize) and animal species are harmed by lower pH or high aluminum levels

resistance of acid rain depends on…

amount of alkali material is present in soil and bedrock

what is the pH of acid rain
