Explore the processes of crustal deformation and mountain building in this 46-minute lecture. Delve into the causes of rock deformation, examining elastic, brittle, and ductile deformations. Learn about various fold types, including domes, basins, and monoclines, with a focus on the East Kaibab Monocline in Arizona. Investigate faults and joints as rock structures formed by brittle deformation, and understand the concepts of hanging wall and footwall blocks. Analyze different mountain-building processes, including Andean-type, collisional, and Cordilleran-type orogenies, with examples such as the formation of the Himalayas and Appalachians. Discover the principle of isostasy and its role in shaping Earth's varied topography. Gain insights into erosion and its impact on isostatic adjustment of the crust, providing a comprehensive understanding of the dynamic processes shaping our planet's surface.
