Difference between continental glaciers and valley glaciers? Continental glaciers are known as ice sheets and cover extensive  areas of Antarctica and Greenland. Valley glaciers come from these  ice fields or mountain glaciers and sliâ¦de down the mountainsides  like long ribbons.
A glacier is a large body of ice that formed on land by the compaction and recrystallization of snow, survives year to year, and shows some sign of movement downhill due to gravity. The three main types of valleys are the V-shaped valley, the flat-floored valley, and the U-shaped valley. V-shaped valley is a narrow valley that has a profile suggesting the form of the letter V, characterized by steeply sloping sides. It results from a stream eroding downward, a process referred to as downcutting.
