John Tuzo Wilson

John Tuzo Wilson was a Canadian geophysicist who significantly advanced our understanding of plate tectonics, the theory explaining how Earth's outer shell is divided into large plates that move over time. He proposed the concept of "hot spots," which are volcanic areas fed by underlying mantle plumes, and he was instrumental in developing the theory of transform faults, where plates slide past each other. His work helped clarify how geological features, like earthquakes and volcanoes, are related to the movement of these tectonic plates, shaping our understanding of Earth's dynamic nature.
