Plate Tectonics

Mr. Andersen discusses the science of plate tectonics, its history, and the evidence supporting it. He explains how the movement of tectonic plates is responsible for earthquakes, volcanoes, and the formation of mountains. The video covers different types of plate boundaries and interactions, such as convergent, divergent, and transform boundaries. It also explores the role of convection currents and hot spots in driving plate movements.
