Plate Tectonics and Continental Drift

The video tutorial reviews plate tectonics, covering key terms like Pangaea, lithosphere, and asthenosphere. It explains the continental drift hypothesis by Alfred Wegener and the role of convection currents in moving tectonic plates. The theory of plate tectonics and seafloor spreading is discussed, along with different types of plate boundaries: divergent, convergent, transform, and subduction. Evidence supporting continental drift, such as fossil records and climate features, is presented. The video concludes with a review of Earth's layers, including the inner core, outer core, mantle, and crust.
