In glaciers water becomes into ice
-Ice moves downhill under the force of
gravity.
River and Glacial
Erosion
-It is when ice freezes and sticks to rock. When
the ice moves, large pieces of rock are pulled
away with it.
Corries
-They are also known as cirques or chums. They are deep, rounded hollows with a steep back wall and a rock
basin.
-In most cases, glacier is along an existing river valley, eroding both the floor and the sides of the valley to
form a glacial trough.
-The characteristic V-shape of a river valley is turned into the typical U-shape of
a glaciated valley.
-They result from differences in the rate of erosion between glaciers in the main and in a tributary
valley.
Erratics
-It marks the furthest or maximum point that a glacier
reached.
