Question

पर्याय

• Young fold mountains

• Old fold mountains

• Residual mountains

• Volcanic plateaus

Answer 1

Old fold mountains

Explanation:

Old fold mountains are highly eroded by agents of gradation (such as wind, water, and ice) over long periods. As a result of this extensive erosion, these mountains have gentler slopes, rounded tops, and sculptured domes. Examples of old fold mountains include the Aravalli Range and the Ural Mountains. These characteristics distinguish them from young fold mountains, which are still undergoing tectonic activity and tend to have steeper slopes and sharp peaks.
