Document Summary
9: crags, cracks, and crumples: crustal deformation and mountain building: mountains, attractive landscape features for humans, provide beautiful scenery, refuge from the mundane. Joints: planar rock fractures without offset, result from tensional tectonic stresses, systematic joints occur in parallel sets, minerals can fill joints to form veins, faults. To find this : right lateral opposite block moves to observer"s right. Left lateral opposite block moves to the observer"s left: large strike slip faults may slice the entire lithosphere, fault recognition, continuous features are displaced across a fault, faults may juxtapose different kinds of rock. Isostasy: surface elevation represents a balance between forces, gravitational attraction- pulls plates into the mantle, buoyancy- floats plates on top of the mantle, the term isostatic equilibrium describes this balance. The hanging wall block of a normal faults slides _____ the surface of the fault: a.
