Glacier classification

Just read a comment from Phil stating that I should think about glacier classification, so here is some information on that:

Glacier Classification

Glaciers are classified by either their temperature (warm or cold) or by their geographical location
WARM/COLD
This refers to how a glacier moves across the ground
WARM - underneath the glacier, a film provides lubrication for the glacier to move across the bed. Most Arctic glaciers are warm
-Form at low altitude e.g. French Alps
-High altitude on the glacier and steep relief as the lack of precipitation and warmer temperatures make this necessary
-Base temperature at/close to melting point = pressure causing melting. Some glaciers are in retreat

COLD - do not have this film and are frozen to the bed. Movement for them is slow and only occurs when ice crystals change.
-Generally high altitude, polar areas e.g. Antarctica
-Temperature at the base is below pressure melting point
-Protect the landscape

N.B.
-Basal temperature is important as this determines how quickly glaciers move

GEOGRAPHICAL LOCATION (Previous blog links to this). Each glacier in its own geographical location has its own special characteristics. N.B. -These can be broken down into further classification by the characteristics. This is especially true is defining them by alpine and continental

I found another source which states that glaciers do not have to be solely defined by the two above categories and are sometimes also alpine/mountain and continental glaciers. Another grouping also stated is constrained and unconstrained which is based on whether ice flow is constrained by topographical features. However, I think what matters most is consistency in what term is used, so whatever is chosen/whatever materials used should state the same so students do not think there are hundreds of different classifications. Nevertheless, this is not to say they should not be made aware of them
