Answer:
Cirques often contain small lakes called tarn.
Step-by-step explanation:
Cirque is a depression or a valley-like formation developed from the erosion of the glacier. They are formed in the mountain ranges. The slopes are steep and melted ice flows down to the floor.
The floor of a cirque is a bowl-shaped structure. The ice from all the sides from melting glaciers fill in the floor. When the glacier melts and slides the sides of the cirque, the floor converts into a lake. This small lake is called a tarn.
