Answers
Ans
An armchair like depression caused by glacial erosion is called cirque or corrie.
Explanation.
cirque is formed when, snow accumulates into shallow depression on the side of the mountain. freezing in winter and thawing in summer causes rocks to wither and break up resulting into enlargement of the hollow. Accumulated ice advances by slipping down slope. A deep crevice called bergshrund develops at the top of ice due to unequal movement. Freezing occur deep down the bergshrund causing the back wall and sides to be steepened by plucking. Plucked debris is carried forward scratching the floor of the basin deepening it forming the cirque or corrie which looks like an armchair.
