GEOSC 010 Chapter Notes - Chapter 14: Continental Crust, Diorite, Mantle Convection
Document Summary
Learning objective: locate and name earths major mountain belts on a world map, plate tectonics model and the major mountain belt formation. Mountains arise from the terrain in isolated formations or in a chain or belt of mountains. Young belts or chains of mountains have formed in recent geological history. The terrain folds and thrusts upward on a fault line. A compressional mountain has a series of folds made up of sedimentary and crystalline rock. See figure 14. 1 to view the earth"s major mountain belts. Convergent plate boundaries create thrust and the stress of the terrain form mountains under the plate tectonics model. Learning objectives: list the four major features of a subduction zone, describe how back-arc basins form. Subduction zones feature four regions: volcanic arc explains how volcanos and an island are formed by two slabs converging together leading one side to move under the other.
