Glaciation trabajo de sergio gutierrez fernandez

By: Sergio Gutierrez Fernandez

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.
