Mountains are jagged because that is how they are formed. As they get older, erosion will begin to smooth them out so they appear rounder.
Can anytone tell me the range of mountains with jagged peaks - i - r - a Sierra

Wind and water erosion makes the mountains smooth.
Jagged mountains peaks become more rounded by the process of weathering. This occurs as wind and rain slowly eat away at the mountain, removing tiny bits of the rocks at a time until the mountains look more rounded than jagged.
Weathering rounded the mountains by breaking down jagged peaks.
The Appalachian Mountains are older and have undergone more erosion, giving them a smoother appearance. The Rocky Mountains are younger and have experienced more uplift and tectonic activity, resulting in their jagged peaks and rugged terrain.
tall and jagged, creating magnificent scenery
A sierra is a long jagged chain of mountains.
Young mountains are jagged because they have experienced recent tectonic activity that causes the Earth's crust to rapidly rise and fold. This process, known as orogeny, results in steep, rugged peaks and ridges. Over time, weathering and erosion will gradually wear down these jagged features, resulting in smoother, rounder mountains.
young mountains are jagged on top, older mountains are smoother
The Appalachian mountains are about 400-500 million years old and have thus been eroded down. The Rocky mountains are very young (they are still being built) and are therefore much higher and jagged as the forces of erosion have not yet had time to grind them away.
Folded mountains have jagged peaks because the layers of rock are folded and bent during the tectonic processes that create the mountains. This folding results in fractures and weaknesses along the rock layers, which can lead to erosion and the formation of sharp, jagged peaks over time.
