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.
Glacial Deposition. Glacial deposition occurs during Glaciation. It refers to the various means by which materials carried by a glacier can be released from the ice and deposited on underlying surfaces or in surrounding areas. Glacial deposition can occur directly from the glacier itself or from several associated processes involving glacial meltwater.
