Which region is the largest geographic region among the following options?

• A. Appalachian Plateau
• B. Coastal Plain
• C. Blue Ridge
• D. Valley and Ridge

Answer: (B)

Understanding how big each region is helps explain why the Coastal Plain is the largest. The Coastal Plain is a broad, flat, low-lying area that runs along the coast and stretches a long distance inland, covering much more land than the other regions. The Blue Ridge is a mountainous region with high peaks, but it isn’t very wide. The Valley and Ridge forms a long, narrow belt of alternating valleys and ridges. The Appalachian Plateau sits in the northwest as a smaller elevated area. Because of its wide expanse and flat terrain, the Coastal Plain covers more area than the others.
