Cold based glaciers:
Are frozen to the bedrock all year round as the temperature of the ice stays at zero degrees constantly
Tend to move via internal deformation as there is no water for basal sliding to occur
Move slowly- causing less erosion to occur
Found at high latitudes
Examples of cold-based glaciers are the Antarctic and Greenland ice sheets
Warm based glaciers
Are not frozen to the bedrock all year round
The temperature of these glaciers is not constantly below freezing so water exists within the ice
The water acts as a lubricant so basal sliding can occur
As basal sliding can occur, warm based glaciers have a faster rate of movement than cold based glaciers and so carry out more erosion
Warm based glaciers tend to be found at lower latitudes
Examples include glaciers found in mountain ranges such as the Alps
