An area under tension will often have Multiple mountain ranges as a result. Slide 13: Basin and range province: tilted fault-block mountains in Nevada. The results of a horst and graben system. Nevada is under tension Because of rising magma which is unzipping the system, all the way From Baja California Sierra Nevada and Wasatch Ranges part of this system Slide 14: REVERSE FAULTS: Hanging wall moves up relative to footwall Result of compression: plates colliding Two types: low-angle or thrust faults, and high-angle reverse faults Individual layers can move 100’s of kilometers Alps are a great example Slide 15: Thrust faults main cause Of folded mountains Slide 16: Appalachian Mountains of the US Slide 17: Atlas Mountains, Northern Africa Slide 18: Classic folded terrain: well-developed anticline Slide 19: ZAGROS MTS PERSIAN GULF Alternating Anticlines and Synclines Slide 20: High-angle reverse faults Forms “Sawtooth Mtns” Flatirons classic example Sawtooth effect result of Differential erosion Slide 21: White Cloud peak SAWTOOTH RANGE, IDAHO Alice Lake Slide 22: COMPLEX MOUNTAINS Tend to have a little of Everything: volcanoes, Folds, thrust faults, normal faults ALPS HIMALAYAS You do not have the permission to view this presentation.
