The Plate Tectonics Revolution: Crash Course Geography

The video explores the development and significance of the plate tectonics theory, which explains Earth's structure and geological activity. It traces the history from early speculations to Wegener's continental drift theory, and the subsequent discoveries of ocean floor features by Heezen and Tharp. The concept of seafloor spreading, supported by paleomagnetic evidence, provided the missing link for Wegener's theory. The video also discusses subduction zones, types of plate boundaries, and the modern understanding of plate tectonics, highlighting ongoing research and future exploration.
