Explanation
Anticline – Anticlines are upward-arching folds in rock layers, with the oldest layers found at the core of the fold.
Syncline – Synclines are downward-bending folds, where the youngest rock layers are found at the core of the fold.
Monocline – A monocline is a fold that involves a single bend in otherwise horizontal or gently dipping rock layers, often caused by faulting below the surface.
Recumbent Fold – A recumbent fold is formed when compressional forces cause the limbs of a fold to become nearly horizontal, resulting in a fold that appears to "lie down."
