What is the major landform located between the Appalachian and Rocky Mountains?

• A. The Interior Plains
• B. The Coastal Plain
• C. The Great Basin
• D. The Canadian Shield

Answer: (A)

Think about how land forms are arranged across the continent. Between the tall Appalachian Mountains in the east and the western Rocky Mountains lies a wide, flat region known as the Interior Plains. This broad area stretches across much of the central United States and into Canada, featuring plains and prairies rather than mountains. That makes it the major landform between the Appalachians and the Rockies.

The Coastal Plain is near the east coast and not between those two mountain ranges. The Great Basin sits between the Sierra Nevada and the Rockies in the western part of the country, not between the Appalachian and Rocky Mountains. The Canadian Shield is a large, old rocky area in Canada, far north and not the central plains in the U.S. between the two mountain systems.
