Strata can be cut by other geologic features, such as faults or intrusions. A fault is a crack in Earth’s crust. WebDec 26, 2015 · A wave-like geologic structure that forms when rocks deform by bending instead of breaking under compressional stress. Anticlines are arch-shaped folds in which rock layers are upwardly convex. The oldest rock layers form the core of the fold, and outward from the core progressively younger rocks occur. A syncline is the opposite …

WebRock can fold either symmetrically or asymmetrically. The upfolds are anticlines and the downfolds are synclines. Severely folded and faulted rocks are called nappes. In asymmetric folding there may also be recumbent and overturned folds. The mountains such formed are usually greater in length instead of breadth.
