A cirque is a bowl-shaped depression formed by glacial erosion, typically found in mountainous regions. It often features steep sides and a flat floor, which can collect snow and ice. A tarn is a small mountain lake that forms in the basin of a cirque when the melted water accumulates. Thus, a cirque without a tarn would be a glacial depression that lacks this body of water, potentially dry or filled with sediment instead.

What is a small lake in a cirque?
A small lake in a cirque is called a tarn. This type of lake forms in a glacial cirque, which is a bowl-shaped depression carved out by a glacier. Tarns are often found at the base of a cirque or in the floor of the depression.
What is the difference between a lake and a tarn?
A ' Tarn' is a mountain lake or pool formed in a cirque excavated by a glacier.
What is a glacier formed lake?
A tarn (or corrie loch) is a mountain lake or pool, formed in a cirque excavated by a glacier.
What is the result of cirque erosion or deposition?
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.
What is a cirque?
a cirque is a steep-walled semicircular basin in a mountain (carved by a glacier)
What landform has very steep sides?
A cliff, a mountain, a ravine, a gorge, glacial valley, an arête, a cirque, a tarn. an escarpment are some possibilities.
How is a glacial crique formed?
A glacial cirque is formed when a glacier erodes the headwall of a valley through processes like plucking and abrasion. As the glacier moves downhill, it creates a bowl-shaped depression with steep walls. After the glacier retreats, the cirque may fill with water, forming a tarn or glacial lake.
What is a glacial tarn?
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.
What do you call a small mountain lake that forms in a cirque after the glacier melts?
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.
