The overall topography of the
ice sheet is
controlled both by the basal and peripheral geology and the
mass balance distribution of the
ice sheet.
Ice - sheet volume is controlled by the balance between mass input and mass loss; mass input is almost entirely due to snowfall, and mass loss is from iceberg calving supplied by flow of the ice sheet, or runoff of melt wat

Pritchard points out that basal melt is a
control on total
mass waste ``... through a reduction in buttressing of the adjacent
ice sheet leading to accelerated glacier flow.»
