MORPHOCLIMATIC SYSTEMS

Glacier 

They are in high areas. 

The temperature must be below zero. The river valleys are V-shaped , and are shaped glacial valleys U. 

The large ice erosive capacity of these materials is due to the dragging . If a glacier melts, the material that has been dragging , stay where they are. 

In the tonge of glaciers lot of fractures appear.

  Parts:

     -Glacier cycle: It's a great depression surrounded by mountains that have accumulated large amount of ice.

     -Glacier tonge: It is a large mass of ice flowing down the slopes of the mountain moved by gravity

     -Ablation zone: In this area the ice melts, rising from the tongue, hard, a stream or river, as the case of the Rhone.

Glacier modeling

The agent acting is ice and more frequent process is the gélifraction.

The scree are rock glaciers (when the glacier disappears, the bedrock that is)

Stone wedges and polygon soils (are typical landscapes of modeling glacier)

Floor cushion (the ground freezes and melt water is aerated and becomes soft and fluffy)

Permafrost (a soil that is permanently frozen)
