What are the examples of Piedmont plateaus?

The Piedmont plateaus are characterized by gently rolling hills and are primarily found in the eastern United States. Prominent examples include the Piedmont region of North Carolina, which extends into Virginia and Georgia, as well as the Piedmont region of Pennsylvania. Other notable examples are the plateaus in the Appalachian foothills, where the terrain transitions from the mountains to the coastal plains. These areas are known for their fertile soil and diverse ecosystems.
