Answer Details

The older fold mountains are much lower in elevation and less rugged than the younger ones largely because they have experienced a longer period of denudation. Denudation is the process of wearing away the surface of the Earth through the combined action of weathering, erosion, and transportation. Over time, the older mountains have been subjected to a longer period of these processes, resulting in their lower elevation and less rugged appearance compared to the younger fold mountains that have not been subjected to the same level of denudation.
