Causes of Acid Rain - compounds like nitrogen oxides and sulfur dioxide are released into the atmosphere
- these compounds combine with water, oxygen, and other chemicals to create more acidic compounds - these compounds then fall as acid rain |
Environmental Effects - acid rain percolates into the soil and dissolves nutrients that trees need
- acid rain also causes the release of aluminum into the soil which hinders trees' ability to absorb water - trees deprived of vital nutrients become more vulnerable to infection, insects, and cold weather |
