Webfold, in geology, undulation or waves in the stratified rocks of Earth’s crust. Stratified rocks were originally formed from sediments that were deposited in flat horizontal sheets, but in a number of places the strata are no longer horizontal but have been warped. Sometimes the warping is so gentle that the inclination of the strata is barely perceptible, or the warping … WebLayers of rocks can be faulted, folded and tilted by large forces within the Earth’s crust. The study of these changes can give information about the strength and direction of the forces involved. Sedimentary rocks – layers of rock fragments that were compressed and cemented together. They often contain fossils.
