Structural Geology and Mountain Formation

This video tutorial covers structural geology and mountain building. It explains the differences between elastic and plastic deformation, types of folds and faults, and the processes contributing to mountain building. The video also describes the four main mountain types: fault-block, folded, volcanic, and island arc volcanoes, providing examples of each. The tutorial aims to equip viewers with the ability to identify geological structures using block diagrams and maps.
