dome
The broad areas of folded rock layers that resemble a bowl turned right-side up are called domes.
To get the answer to this question, you can start by understanding the definitions of the given options: domes, basins, horsts, and monoclines.
- Domes: A dome is a geological structure characterized by upward, convex layers of rock that resemble an overturned bowl or dome-shaped structure. The layers in a dome usually dip away from a central point.
- Basins: A basin is a geological structure that is characterized by downward, concave layers of rock, resembling a bowl turned upside down. The layers in a basin dip towards a central point.
- Horsts: Horsts are elevated blocks of the Earth's crust that are bounded by faults or fractures. They are characterized by uplifted, relatively flat and block-like areas of land.
- Monoclines: Monoclines are simple, large-scale folds in rock layers, typically in the form of a single, step-like bend in otherwise horizontal rock strata.
Based on the descriptions, the option "domes" fits the description of broad areas of folded rock layers that resemble a bowl turned right-side up. Therefore, the correct answer to the question would be domes.
