WebThis has been caused by enormous pressure in the earth's crust resulting in slow bending of the rocks. The dip of a bed of rock is the greatest angle of inclination at which the bed is tilted from the horizontal. The strike of a bed of rock is the direction of a horizontal line on the bedding plane.

A fold is most easily observed where flat layers of rock were compressed or squeezed inward. As stress was applied, the rock layers bent and folded. Cracks sometimes appear in or near a fold, but most commonly the rock layers remain intact. nike dunk low off-white lot 35

WebThe crust is the thinnest layer of the Earth. It has an average thickness of about 18 miles (30km) below land, and around 6 miles (10km) below the oceans. The crust is the layer that makes up the Earth’s surface and it lies on top of a harder layer, called the mantle. Together, the crust and the upper mantle form the Earth’s outer shell. WebFolds are types of geological structures that arise due to the curving or bending of Earth’s crust. Folds are secondary tectonic structures that have formed after the deposition of rocks in response to compressional stress.

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.
