Mountain Belts - Birth, Growth, and Destruction

Explore the fascinating world of mountain formation, evolution, and eventual destruction in this 27-minute taster lecture. Discover the importance of mountain-building events, learn basic tectonic principles, and delve into the stages of mountain development from birth to continental collision. Examine critical taper theory, megathrust events, and the transition from subduction to collision. Investigate real-world examples such as the growing tectonic folds of the Tripura Ranges and Taiwan's single faulting/uplift event. Understand the role of gravity in shaping mountain ranges, including topography and gravity anomalies, weak layers beneath mountains, and gravitational collapse. Conclude by considering the future of collapsed mountain ranges in this informative lecture from Royal Holloway, University of London.
