Ablation = the process of wastage of snow or ice, especially by melting.
Accumulation = the net gain in ice mass. The sources of accumulation are direct snowfall and avalanching from higher slopes.
Extensional Flow = this is the extension and related thinning of glacier ice in those zones where velocity increases.
Compressional Flow= this is the type of glacier flow whereby a reduction in velocity leads to an increase in thickness of a glacier.
Glacial = a period of time when masses of ice develop and advance into lower altitudes due to a sustained decline in temperature. Extensive continental ice sheets form during such…
