How can alpine glaciers create these features?

Alpine glaciers create distinctive features through processes of erosion and deposition. As glaciers move down mountainous terrain, they carve out U-shaped valleys and sharp peaks, known as horns, through abrasion and plucking of rock. Additionally, when glaciers melt, they deposit sediment in the form of moraines, which are ridges of debris left at the glacier's edge. These processes collectively shape the dramatic landscapes characteristic of alpine environments.
