A small mountain lake that forms in a cirque after a glacier melts is called a "tarn." Tarns are typically surrounded by steep cliffs and are often found in mountainous regions where glaciers once existed. They can vary in size and depth, and their formation is a result of glacial activity that carves out the landscape.
What can happen when the glacier melts in a cirque
the glacier dropped small rocks as it melted. An erratic is a large boulder left behind after a glacier has melted

A tarn is a small, steep-banked mountain lake, formed when a glacier advancing down a slope scoops material out of the ground in a "cirque" at the base of the slope. (Essentially, it continues downward into the ground before moving horizontally again.) When the glacier melts, the depression can fill with water, and is refilled by melting snow unless it becomes filled by silt.
A glacier forms under certain terrain conditions and where more snow falls in the winter than melts in the summer.

Cirque erosion results in the formation of bowl-shaped depressions at the head of a valley glacier. Deposition can occur when the glacier melts, depositing sediment and creating a small lake called a tarn in the cirque basin.

Corries begin as shallow hollows on a mountain side fill with snow. As the glacier gets bigger, it begins to move down the slope. There is a reduced rate of erosion at the front of the corrie as the ice is thinner here. This makes a moraine. When the ice melts, water may get trapped behind creating a corrie lake or tarn. All of this forms a corrie.

A glacier is made up of ice, a solid, but the ice flows, melts, and recrystallizes regularly.
