Glaciers In this weeks lessons we will be investigating Glaciers and how they erode, transport and deposit material. By the end of today's lesson you will be able to describe how corries are created.

Glacier System Revision Complete worksheet 19.1 from The New Wider World Resource Booklet.

How is a corrie formed? Snow collects in a natural hollow on the side of a mountain. Over time, further snow collects in the hollow. This extra weight compresses the snow underneath, turning it into ice. rock lip The hollow is deepened and widened by the corrie glacier through the processes of abrasion and plucking. This overdeepening leads to an ‘armchair’ shape characteristic of a corrie and causes a ‘rock lip’ to be formed.
