Glacial budget definition
WebThe glacier mass budget is characteristically evaluated over one hydrological year (October 1–September 30) and is reported as water equivalent per unit area per year (m a −1). … WebThe relation between accumulation and ablation for a glacier (also called 'glacier budget'). It is positive if over a year there is more accumulation than ablation. It is negative if there is more ablation than accumulation. moraine Accumulations of rock debris being transported or deposited by a glacier.

WebTerms in this set (15) Glacial ice sheets are the largest glaciers and they currently cover Greenland and Antartica If the glacial budget is balanced (accumulating equals wastage), then the terminus of the glacier is stationary what are erosional features produced by valley/alpine glaciers. Cirques the term drift WebGlacial movement is the way in which a glacier stays in motion (internal deformation, basal slippage). This movement depends largely on the type of glacier (warm, cold, or polythermal-based). Types of glaciers
WebIt's useful to have a definition of glacial movement before we look more closely at how it happens. Glacial movement is the way in which a glacier stays in motion (internal …
WebA glacier is a large, perennial accumulation of crystalline ice, snow, rock, sediment, and often liquid water that originates on land and moves down slope under the influence of its own weight and gravity.
