If the planet were to cool in the future, snow may begin to accumulate in the head of a glacier more rapidly than it would melt in the zone of wastage. In these circumstances, the terminus of the glacier would .

The glaciers will accumulate more in amount when the planet cools, and this will result in the slow expansion of glaciers, extending horizontally and downward, due to the pressure exerted by the glaciers. The glaciers will be rapidly accumulated in the glacier head in comparison to the zone of wastage, which covers the region below the snowline.  These glaciers moves at a fairly slow rate, under the influence of gravity.

As the planet cools, the terminus of the glaciers (glacier end or toe) will expand and will be distributed more outward and downward, and there will be more quantity of snow in a cool planet.
