Tensional geology
WebFolding and faulting are two terms in geology used to describe the changes the surface of the earth goes through. In structural geology, a fold is a stack of originally planar surfaces, such as sedimentary strata, that are bent or curved during permanent deformation. ... Faults are due to tensional forces along which displacements of rocks take ... WebTo experience the three types of material stress related to rocks—tensional, compressional and shear—students break bars of soap using only their hands. They apply force created by the muscles in their own hands to put pressure on the soap, a model for the larger scale, real-world phenomena that forms, shapes and moves the rocks of our planet. They also …

WebColumnar jointing forms in lava flows, sills, dikes, ignimbrites (ashflow tuffs), and shallow intrusions of all compositions. Most columns are straight with parallel sides and diameters from a few centimeters to 3 m. Some columns are curved and vary in width. Columns can reach heights of 30 m. http://rogermarjoribanks.info/sense-movement-structures-part-1-theory/
