Which of the following best describes the Great Dismal Swamp's region?

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

Answer: (C)

The main idea is understanding where different Virginia regions sit and what each region tends to be like. The Great Dismal Swamp is in the Coastal Plain, which is the low, flat land near the Atlantic coast. This area has plenty of wetlands and marshy places, so a large swamp fits there well.

In contrast, the Piedmont is the inland area with rolling hills, the Blue Ridge is a mountainous region, and the Valley and Ridge features long valleys separated by ridges. Those landscapes aren’t swampy lowlands like the Coastal Plain. So the swamp’s flat, water-rich environment belongs to the Coastal Plain.
