GEOL 100 Lecture Notes - Lecture 12: Anticline, Red Sea Rift, Rhine
Document Summary
Undeformed: rocks that are not tilted, bent, or fractured (like sedimentary flats). Compressive: squeezes from the sides and makes it smaller. shorter. Tensional: pushes down and stretches it out. longer. Shearing: pushes from two sides and literally forces it into a diagonal to one of the tectonic forces. The amount of push/pull/shear that is felt when subjected. Strain: the change in shape that happens in response to stress. Dip: the amount of tilting (in degrees) that the rock inclines/declines from the. Strike: the direction (n/w/s/e) that the intersection of rock layers lays in. This is perpendicular to the direction of the dip. Depends on the kind of rock, temp , pressure, magnitude, speed of force . Likely fold/bend because it can be easily molded. Example: the valley and ridge of the appalachian mountains. Anticlines: upfolds - arches made up of layered rocks.
