Folds

Fold is when one or a stack of originally flat and planar surfaces, such as sedimentary strata, are bent or curved as a result of plastic deformation.

Two types of folds:

Anticline: is a fold that is convex

Syncline: is a fold that is concave

And in this picture we can see the differents parts of a fold
