Earth Science - Continental Drift and Plate Tectonics

Explore the fascinating journey from continental drift to plate tectonics in this 42-minute video lecture. Delve into compelling evidence supporting these theories, including the continental jigsaw puzzle, matching fossils across seas, rock types, geologic features, and ancient climates. Examine the great debate surrounding these ideas and learn about Earth's lithosphere, asthenosphere, and tectonic plates. Investigate plate movements and various boundary types, including divergent (oceanic ridges, seafloor spreading, continental rifting), convergent (oceanic-continental, oceanic-oceanic, continental-continental), and transform boundaries. Enhance your understanding with supplementary mobile field trip videos and a convergent boundary video for a comprehensive exploration of Earth's dynamic processes.
