Question

Quizplus · Accepted Answer

Glaciers form when snow accumulates to form ice, which then begins to flow. This process requires time and pressure, which compresses the snow into ice and causes it to move downhill under its own weight. The temperature can be above freezing during the day, but the glacier will still continue to exist as long as it gains more snow than it loses through melting or evaporation. A summer climate can still occur in areas with glaciers, but the glacier itself will remain frozen and continue to flow. A solid mass of snow moving downhill is called an avalanche and is different from a glacier.
