Explain the difference between the way glaciers and sea ice accumulate ice
What will be an ideal response?
Glaciers accumulate ice through snowfall on the glacier surface in the accumulation zone (the area at elevations above the summer snow melt). As the snow accumulates it is converted into ice through the process described in answer to question 6 above. Glaciers, therefore, accumulate new ice at the surface, on top of the old ice. Sea ice grows by freezing sea water below the ice pack. Unlike glaciers, therefore, sea ice grows in thickness by accumulating ice at its base. The newer ice is on the bottom and the older ice is on the top of the ice pack.
