Final answer:
The Black Hills of South Dakota are an example of a geological dome, an uplifted structure where rock layers dip away from the center.
Step-by-step explanation:
The Black Hills of South Dakota are a good example of a dome. A geological dome is a structural feature where rock layers are pushed upwards to form a 'dome-like' shape. Unlike synclines and anticlines, which are folds resulting from the compression of the Earth's crust, a dome represents an uplifted area where the rock layers dip away from the center in all directions, similar to an overturned bowl. This geological formation often exposes the oldest rocks at its core, with progressively younger rocks found towards its outer layers. The Black Hills have this characteristic dome structure, making this region rich in geological history and a focus for many studies.
