What conditions are needed for glaciers to form and be maintained? As a result of these conditions,
where are glaciers found? What will be an ideal response?
Glaciers form where there is a lot of snowfall and temperatures are cold. Since temperatures are colder
at higher altitudes and latitudes, these regions have glaciers if they receive enough snow. The
mountains of California receive a lot of snow, but only very high mountains are cold enough to
maintain glaciers. Glaciers cover the continents in the far north and south, e.g., Greenland and
Antarctica.
