Abstract
This subject will discuss how the Pacific Southwest piece was formed according to the theory of plate tectonics. It will apologise the theory of plate tectonics, which is the theory of how the continents move around on the mantle, and identify factors that influence the location and intensity of existencequakes and vol tidy sumoes for the region. The San Andreas Fault dictated in California, is a crack in the crust of the earth and is the main factor behind the earthquakes that shake the Pacific Southwest. The teddy causes earthquakes as the west side of the plates moves north. The paper will too describe the main movement within the plate tectonics theory that shaped the form and composition of the selected region. It will also discuss the various geological events that occurred and the various types of rocks that the geological events formed. Finally, the paper will discuss the importance and economic value of rocks in the Pacific Southwest.
Explanation of the theory of plate tectonics
The plate tectonic theory is an amazing theory.
It begins with shaping the lithosphere, which is the outer layer of the earth. The lithosphere is relativity thin compared to the await of the Earth. The lithosphere lies on top of a much weaker contentedness that is constantly in motion. This is called the asthenosphere, which is weak because of being at a temperature that is close to the melting point. The lithosphere maintains a solid recount that allows it to float atop the asthenosphere (Merali, Z., & Skinner, B. J., 2009). The lithosphere broke arrive at into seven large plates, each of these plates expand thousands of kilometers. When tectonic plates slew against one another, split apart, or collide the result of this can be very devastating. The outcomes of these actions may cause earthquakes, formation...
