Deformation and Mountain Building

Learn about brittle and ductile deformation, stress and strain concepts, faults and folds in the Earth's crust, types of stress including compression and extension, various fault types such as dip-slip, thrust, and transform faults, and how these processes contribute to mountain building. Explore topics like synclines, anticlines, and monoclines, and understand the role of isostasy in mountain formation.
