Most of the sediment that glaciers carry comes from ________
What is a glacier’s slope?
Many of the sediment which glaciers have comes from slopes that flank the glaciers and the bedrock below the glacier. Valley glaciers tend to be smaller than ice sheets. The main difference between the two classes, though, is how they relate to the topography beneath them. Valley glaciers are ice rivers that are usually found in mountainous areas. Their flow patterns are controlled by the high relief in these areas. Many large valley glacier systems look like the roots of a plant when seen on a map. This is because they are made up of many smaller glaciers that join together to make a large “trunk glacier.”
