Valley Glacier
Valley glacier explained in an easy to understand way:


Imagine trying to pour a thick smoothie through a narrow straw. Just like the smoothie slowly squeezes its way through the constricted space, a valley glacier inches its way down a mountain valley. The thick, slow-moving smoothie represents the dense ice of the glacier, while the narrow straw is akin to the confined mountain valley channeling the glacier's flow.
