Mount Mitchell Acid RainIn 1915, Mount Mitchell was designated as North Carolinas first state park and was covered by a dense forest. Today, the forest has thinned considerably as a result of pollution and acid deposition. According to the Division of Parks and Recreation, the forest experiences acid fogs approximately 80% of the year. State officials have determined that much of the air pollution in North Carolina originates in other states and is transported by winds. In 2004, the Environmental Protection Agency began to develop a plan to reduce harmful emissions in states that are upwind from North Carolina.How will acid deposition most likely affect the carbon cycle on Mount Mitchell?

Mount Mitchell Acid RainIn 1915, Mount Mitchell was designated as North Carolina’s first state park and was covered by a dense forest. Today, the forest has thinned considerably as a result of pollution and acid deposition. According to the Division of Parks and Recreation, the forest experiences acid fogs approximately 80% of the year. State officials have determined that much of the air pollution in North Carolina originates in other states and is transported by winds. In 2004, the Environmental Protection Agency began to develop a plan to reduce harmful emissions in states that are “upwind” from North Carolina.How will acid deposition most likely affect the carbon cycle on Mount Mitchell?

A	Sulfur dioxide will replace carbon dioxide in the carbon cycle.
B	With fewer trees, the park will store a greater amount of carbon dioxide.
C	Acid deposition will have no direct effect on the carbon cycle.
D	There will be fewer trees to absorb carbon dioxide from the atmosphere.

Explanation:

Detailed explanation-1: -Power plants release the majority of sulfur dioxide and much of the nitrogen oxides when they burn fossil fuels, such as coal, to produce electricity. In addition, the exhaust from cars, trucks, and buses releases nitrogen oxides and sulfur dioxide into the air. These pollutants cause acid rain.

Detailed explanation-2: -The event was of great significance in the history of public health, resulting in the passing of the Clean Air Act of 1956, which regulated the use of air pollutants. The type of fog, containing poisonous sulphur dioxide, was common in London at the time, arising from the widespread use of coal.

Detailed explanation-3: -How will acid deposition most likely affect the carbon cycle on Mount Mitchell? Acid deposition will have no direct effect on the carbon cycle. Sulfur dioxide will replace carbon dioxide in the carbon cycle.
