Acid rain occurs when sulfur dioxide and nitrogen oxides are amitted into the atmosphere, undergo chemical transformations and are absorbed byk water droplets in clouds. The droplets then fall to earth as rain, snow, mist, dry dust, hail or sleet. This can increase the acidity of the soil and affect the chemical balance of lakes and streams. Acid rain is a serious environmental problem that affects large parts of the US and Canada" Acid rain accelerates weathering in carbonate rocks and accelerates building weathering.
It also contributes to acidification of rivers, streams and forest damage at high elevations. When the acid builds up in rivers and streams it can kill fish.
Acid rain can slow the growth of forests, cause leaves and needles to turn brown and fall off and die. In extreme cases trees or whole areas of forest can die. Soil biology can be seriously damaged by acid rain.
