Ice calving. Ice calving, also known as glacier calving or iceberg calving, is the breaking of ice chunks from the edge of a glacier. It is a form of ice ablation or ice disruption and is normally caused by the glacier expanding. It is the sudden release and breaking away of a mass of ice from a glacier, iceberg, ice front, ice shelf, or crevasse.
Alpine Glacier - Most glaciers that form in a mountain are known as alpine glaciers. There are several subtypes of alpine glaciers: Cirque: a cirque is a bowl shaped hollow at the head of a valley. Within a cirque lies a snowfield, the place where snow accumulates to form a cirque glacier. Valley: any glacier that resides in an area eroded by stream action is called a valley glacier.
