ERS120H5 Lecture Notes - Lecture 19: Continental Crust, Subduction, Oceanic Crust
Document Summary
Short answer question second half of the semester. The faults rotate around and creates rift area to rise and form mountains. Continental collision: large scale mountain building events, 2 continental crusts collide with each other and it creates a suture zone and the mountain range is where the 2 crusts and joined together and thickened. Fold-thrust belt: the fold-thrust belt is being shortened and folded together, the belt is like a bulldozer pulling a pile a sand together and creating thrusts, all the black lines on the canadian rockies are thrust belts. Plateaus: it is a significant aerial extent, always high elevation (3-5000 above sea level, low-relief, thick crust (50-70 km, tibet has a dry climate because the elevation and different weather. There is a lot of warm moist air hitting the plateau and is drawn up and over the mountains. The mounting loses their ability to hold the air and so it goes up and condenses and rains.
