WebFigure 7--Uncomformity is a surface between rock layers that shows the effects of a period of erosion or nondeposition. In this case, the rocks below the wavy line (uncomformity) were deposited, folded to form an anticline, and then eroded to a plain before the rocks above the unconformity were deposited. WebFolds may be defined as undulations or bends or curvatures developed in the rocks of the crust as a result of stresses to which these rocks have been subjected from time to time in the past history of the Earth.
