Glaciation Flashcards
Formation of a corrie
Snow falls in a shallow hollow
More snow falls and it turns to ice
Travels downwards
Freeze thaw and plucking cut at the back wall
abrasion from under the ice deepens it
À rock lip is left where erosion is least
as the ice melts and arm chair shape is left
this fills up with water and become a lake

3or more corries and arêtes erode back to back creating a sharp edge
