A large area of sunken land shaped like a bowl is called a basin.

Here's a breakdown:

* Basin: A large, low-lying area of land, often surrounded by higher elevations. It can be formed by various geological processes, such as tectonic plate movement, erosion, or volcanic activity.

* Shape: The bowl-like shape is a characteristic feature of basins, with the lowest point at the center and the edges gradually sloping upwards.

* Examples: Famous examples of basins include the Great Basin in the western United States, the Amazon Basin in South America, and the Congo Basin in Africa.
