How is an increase in carbon in the atmosphere likely to affect coastal areas such as those in north carolina?
a. it is likely to cause a decrease in flooding.
b. it is likely to cause an increase in plant growth.
c. it is likely to cause a decrease in pollution.
d. it is likely to cause an increase in erosion.

D. It is likely to cause an increase in erosion.

Explanation:

An increase in carbon in the atmosphere is most likely to cause coastal erosion. Coastal erosion is the washing away of the shore as result of waves and storms breaking into them.

When the level of atmospheric carbon increases, more radiation is trapped within earth and this leads to the phenomenon of global warming. As the earth warms, polar ice melts and ocean level rises. More water in the ocean would lead to flooding and generation of disturbances in the ocean. This high volume of water would easily wear and wash away the shores.
