Understanding Earthquakes and Tectonic Plates

Bill Nye explains earthquakes, starting with the Earth's formation from dust and the movement of tectonic plates. He discusses how human activities, like drilling, can induce earthquakes. Emphasizing safety, he advises designing buildings to withstand earthquakes. Nye also covers the history of tectonic plate theory, highlighting Alfred Wegener's contributions and evidence from World War II submarine explorations. He concludes by noting that earthquakes are a natural part of Earth's dynamics.
