Glacial Systems – the Glacial Budget | Geography | tutor2u, 9/15/2020 · Glaciers with positive budgets push outward and downward at their edges; they are called advancing glaciers. Those with negative budgets grow smaller and their edges melt back; they are receding glaciers. The Glaciers budget is the balance or lack of balance between accumulation and the loss of ice. The loss of ice at the lower end of the Glacier is called ablation. If accumulation exceeds.
Evaporation and meltwater rates are low, so in the colder, upper zone most of the glacier remains as ice that is periodically added to. This part of a glacier is known as the zone of accumulation and results in an increase in mass within the glacier . In the lower part of the glacier , near the snout, the reverse will occur and outputs exceed …
An expanding glacier is said to have a positive budget and, as a result, is said to be advancing .A shrinking glacier is said to have a negative budget and, and as a result, is said to be retreating. Throughout the 20th century most glaciers on a global basis have been retreating. Movement varies from a few millimeters a day to more than 15 meters a day. The snow line will retract due to the …
