Ablation (1) Combined processes (such as sublimation, fusion or melting, evaporation) which remove snow or ice from the surface of a glacier or from a snow-field. Also used to express the quantity lost by these processes.
ablation (glacial) All processes, which include melting, evaporation (sublimation), wind erosion, and calving (breaking off of ice masses), that remove snow or ice from a glacier or snowfield.
ablation"1. All processes that remove snow, ice, or water from a glacier, snowfield, etc.; in this sense, the opposite of accumulation. These processes include melting, evaporation, calving, wind erosion, and an avalanche.

Ablation: Depletion of snow and ice by melting and evaporation.
Abutment: The part of a valley or canyon wall against which a dam is constructed. Right and left abutments are those on respective sides of an observer looking downstream.

The line separating the accumulation area from the ablation areaFirst Law of ThermodynamicsThe law of physics that states that the heat absorbed by a system either raises the internal energy of the system or does work on the environment.
Snow Accumulation and Ablation ModelIn hydrologic terms, a model which simulates snow pack accumulation, heat exchange at the air-snow interface, areal extent of snow cover, heat storage within the snow pack, liquid water retention, ...
In hydrologic terms, the highest level to which the fresh snow on a glacier's surface retreats during the melting season. The line separating the accumulation area from the ablation area

accumulation - 1. See snow accumulation. 2. In glaciology, the quantity of snow or other solid form of water added to a glacier or snowfield by alimentation; the opposite of ablation. Compare snowpack.
