Anticlines (the characteristic on the left half) are downward-curving (convex) folds inwards stone that resembles an arch. The primal part, existence the well-nigh exposed to erosion, display the oldest department of rock. Synclines (the characteristic inwards the center) are upward-curving (concave) folds inwards stone that resemble a trough. The primal business office contains the youngest department of rock.
