How is a corrie formed in 8 steps?

Answer 1

A corrie, also known as a cirque, is formed through a combination of glacial and erosional processes. First, snow accumulates in a hollow on a mountain side, compacting into ice. As the ice thickens, it begins to move, eroding the underlying rock through processes like plucking and abrasion. Over time, this erosion deepens and shapes the hollow into a bowl-like feature, often with steep sides and a lip at the front, which can later become a lake if water collects in it.
