Mountain and Rift Building
New studies supporting and old study named "The Wilson Tectonic Cycle" support how ocean basins opened and closed along the North American eastern seaboard. The new evidence is that quarts is the key role in causing he Earth's surface to fold, stretch, crack, and wrinkle. The evidence comes from places where the Great Plains meet the Rocky Mountains, where the crust under the plains has nearly no quarts in it while the Rockies have a high quantity of quartz and there for took the effect of the earths movement. The stress of rocks cause the response of earthquakes and mountain building. For a long time rift zones and mountain belts formed at the same location over and over again and with the use of Earthscope Array of seismic stations they were able to determine the thickness along the seismic velocity ratio along the continental crust.
