1. Anticline: Upward folding of rock layers
2. Syncline : Downward folding of rock layers
3. Monocline : A single bend in rock layers
4. Recumbent Fold : Fold with limbs parallel and almost horizontal

How many pairs given above are correctly matched?
(a) Only one pair
(b) Only two pairs
(c) Only three pairs
(d) All four pairs

ONLiNE UPSC · Accepted Answer

Anticline &ndash; Anticlines are upward-arching folds in rock layers, with the oldest layers found at the core of the fold.
Syncline &ndash; Synclines are downward-bending folds, where the youngest rock layers are found at the core of the fold.
Monocline &ndash; 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 &ndash; 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."
