What are 3 features created by alpine glaciers and how are they formed?

Alpine glaciers create several distinctive features, including U-shaped valleys, cirques, and moraines. U-shaped valleys are formed as glaciers carve through mountainous terrain, eroding the sides and base to create a broad, flat valley floor. Cirques are bowl-shaped depressions formed at the head of a glacier, where ice accumulates and scours the rock beneath it. Moraines are accumulations of debris, such as rocks and sediment, that are pushed along and deposited by the glacier as it moves and melts.
