1. Erosion: This is the primary process responsible for rounding mountain peaks. Over long periods, wind, rain, ice, and other weather elements wear down sharp, jagged peaks, gradually smoothing them into rounded shapes.
2. Isostatic uplift: This is a geological process where the Earth's crust rises in response to the removal of weight. This can happen when glaciers melt or when erosion removes a large amount of material from a mountain range. The land beneath the removed material then rises, leading to the formation of high mountains. While isostatic uplift doesn't directly cause rounded peaks, it creates the initial elevation that allows erosion to shape the mountains over time.
