The Blue Ridge Mountains of Virginia are rounder and smoother than the Rocky Mountains of Colorado. What is the best reason for this difference?

• The Blue Ridge Mountains have more plant and animal life that wears them down.

• It is warmer in Virginia, so ice can't form on the mountains to break the rocks apart.

• The Blue Ridge Mountains are much older and have been exposed to more weathering.

• More people drive in the Blue Ridge Mountains. The traffic has worn the mountains down.
