Objectives for Glaciers 1) What do you call the part of the Earth system that remains frozen all year long? The Cryosphere. 2) What is the main requirement to get a glacier, and how does this relate to the snowline? A glacier forms in a place where the total accumulation of snow in the winter is greater than the total amount of ablation in the summer. (Ablation = melting and sublimation) The snowline is the altitude/latitude at which winter snowfall = summer ablation. 3) What are the six fundamental types of glaciers listed in your book (this is a morphological classification)? Cirque glaciers, Valley glaciers, Fjord glaciers, Ice caps, Ice sheets, ice shelves. 4) In a thermal classification of glaciers, what are the two main types? Warm (temperate) glaciers in which the ice is near its pressure-melting point throughout the ice and mass. Cold (polar) glaciers (subpolar – glacier in which the ice mass is generally below the pressure melting point except for summer melting of the upper
