Anticline

A type of fold in the Earth's crust characterized by an arch-like shape where the oldest rock layers are at the center of the fold, usually formed by compressional tectonic forces.

Syncline

A fold in rock layers where the youngest layers are closer to the center of the structure, typically shaped like a trough.

Limestone

A sedimentary rock composed primarily of calcium carbonate (CaCO3) in the form of the mineral calcite, often formed from the skeletal fragments of marine organisms.
