Cyrosphere 2) What is the main requirement to get a glacier, and how does this relate to the snowline? Place total accumulation of snow in the winter is greater than the total amount of ablation in the summer Snowline is the altitude/latitude at which snowfall equals summer ablation 3) What are the six fundamental types of glaciers listed in your book (this is a morphological classification)? 1.
