What is the difference between a cirque and circus?

A cirque is a bowl-shaped depression formed by glacial erosion. It is typically found at the head of a glacial valley. A cirque is formed when a glacier moves down a valley, and the ice erodes the bedrock at the head of the valley. This erosion creates a steep-sided, amphitheater-shaped depression.

A circus is a large, open-air arena or amphitheater. It is typically used for performances, such as plays, concerts, and sports events. A circus can be temporary or permanent. Temporary circuses are often set up in parks or other public spaces, while permanent circuses are usually built in cities.

In summary, the main difference between a cirque and a circus is that a cirque is a natural geographical formation, while a circus is a human-made structure.
