What mountain range forms the border between the eastern United States and the west?

• A. Rocky Mountains
• B. Appalachian Mountains
• C. Sierra Nevada
• D. Great Smoky Mountains

Answer: (B)

The Appalachian Mountains form the border between the eastern United States and the west. This mountain range extends from northern Alabama up to Canada, defining a significant geographical divide. The Appalachians are one of the oldest mountain ranges in North America, shaped by weathering and erosion over millions of years. Their presence has historically impacted settlement patterns, travel routes, and even cultural development in the United States. The range also plays an important role in ecology, as it includes diverse ecosystems and specific climate patterns distinct from those to the west. Understanding this geographical boundary is crucial for historical context as well, as the mountains provided both a natural barrier and a resource-rich area for various settlers and indigenous peoples.
