STRUCTURAL LANDSCAPES ** the relationship between geologic structure & the visible landscape, & how this is formed by various processes ** formed by tectonic forces or stresses: ** these stresses create various features: faults, folds, fractures, and warping : Earthquake Landscapes ** a process whereby rocks on either side of a fault or fracture are displaced relative to the other side ** occurs when the rock is too brittle or inflexible to bend or fold * fracture: crack in rock structure * fault: fracture with displacement of the rock on either side * fault plane: surface of contact along which blocks on either side of a fault move * fault scarp: exposed cliff like face of a fault plane created without significant erosional change Types of Faults : 1) Compressional Faults: compression of crustal rock into a smaller horizontal space; shortening of the crust a) reverse fault: where one block overrides the other block along a deep fault plane
