streams make up about 10 percent of an ice sheet, and they are
fastest moving parts of the ice sheet. Large ice streams can
be 50 kilometers wide and 2,000 meters thick. They can extend
for over 1,000 kilometers. Ice streams usually form in spots
on the ice sheet where water is there. The speed of an ice stream
depends on the smoothness of the ground that it is on and how
slushy the ground is. |

| Ice streams can form on both valley glaciers and continental
glaciers. Ice streams that form on valley glaciers slide in
a narrow pass between mountain sides. On continental glaciers
ice streams form near the shore and are called outlet glaciers.
Outlet glaciers are the point where the ice sheet touches the
edge of the ocean. |
