Features of Glacial Erosion
Remember for each feature you should be able to:
 | Describe its characteristics and explain how it formed; |
| Draw a labelled diagram |
| Name an example; |
Make sure you revise your notes carefully!

IMPORTANT
It is important to remember that fluvioglacial erosion is also responsible for creating landforms, for example spillways (Overflow channels), these occur when proglacial lakes overflow, resulting in intense fluvial erosion resulting in the creation of a deep gorge. (please see your class notes on the effects of glaciation on drainage)
