4

Step-by-step explanation:

Number 4 represents the Appalachian Mountains. They stretch over 2,000 miles long and are the oldest mountain range in North America. They are over 400 million years old.

Answer 2

The answer is 4) Appalachian Mountains.

All the mountain ranges listed have, of course, experienced a certain level of erosion. However, the Appalachian range is the most heavily eroded. It was once almost as high as the Rocky Mountains, which has an elevation of 4,000 meters, but erosion has brought its elevation down to around 2,000.
