Anticline folds.

Folds. Rocks crumple into folds when experiencing a significant amount of stress. A monocline is when the rock bends so that the layers are no longer horizontal. An anticline is when the rock bends up so there is an upward arch. The oldest layer is at the center, and younger layers are outside.Folds jpb, 2020. FOLDS .
