Continental Drift (1980)

The film discusses the theory of plate tectonics and continental drift, explaining how the Earth’s surface has changed over time. It highlights the concept of tectonic plates moving due to convection currents beneath them, leading to geological phenomena such as earthquakes, volcanic eruptions, and the formation of new landmasses. The film uses various examples, including the Mid-Atlantic Ridge, Iceland, and the San Andreas Fault, to illustrate these processes. It emphasizes the evidence supporting plate tectonics, such as the matching coastlines of continents and magnetic banding on the ocean floor, and concludes by indicating that the Earth’s surface will continue to evolve.
