Valley glaciers are smaller and flow down mountain valleys, while ice sheets are enormous and cover large regions such as Antarctica and Greenland.

Valley glaciers are found only at the poles, while ice sheets are found only at the equator.

Valley glaciers are made of liquid water, while ice sheets are made of snow.

Valley glaciers move faster than ice sheets and cover more land area.
