Sedimentation: Sediment is constantly being deposited in the coastal plain by rivers, waves, and currents. This sediment can build up to create new land, such as barrier islands and spits.
Submergence: The coastal plain of North Carolina is slowly sinking beneath the sea level. This submergence is caused by a combination of factors, including the melting of glaciers and the thermal expansion of seawater.
Emergence: In some areas, the coastal plain of North Carolina is actually rising above sea level. This emergence is caused by a combination of factors, including the compaction of sediments and the movement of tectonic plates.
Hurricanes: Hurricanes are a common occurrence in the coastal plain of North Carolina. These storms can cause extensive damage to property and infrastructure, and they can also lead to loss of life.
