Glacier Movement
The action of gravity moves the mass of ice down the slope side.
There are two kinds of motion: a slow sliding motion and an avalanche
like flow. The movement of glacial ice, is a flow similar to
plastic flow and viscous flow. In Valley Glaciers the central
part moves fastest like a stream. Glaciers move from a
millimeter to one meter a day. Valley Glaciers move slow, but
with tremendous force plowing through anything in its way. When
the glacier recedes the glacier leaves its mark by carving out a U
shape through the valley. It happens by the glacier caring
other rock and grinding through the main rock. Making the
