How does and arete form? - Answers

An arete forms through the process of glacial erosion, where glaciers carve sharp ridges and peaks in mountainous regions. As glaciers move, they erode the rock on either side, leading to the creation of steep, narrow ridges. The continuous action of freezing and thawing can further shape the arete, enhancing its distinctiveness. Over time, the combination of these geological processes results in the formation of a sharp, jagged ridge characteristic of aretes.
