What theory did tuzo Wilson develop?

Tuzo Wilson developed the theory of "hotspots" in geology, which explains the formation of volcanic islands and chains. According to this theory, hotspots are areas where plumes of hot mantle material rise to the Earth's surface, creating volcanic activity independent of tectonic plate boundaries. This concept helps to explain the existence of volcanic islands like the Hawaiian Islands, which formed as the Pacific Plate moved over a stationary hotspot. Wilson's work significantly advanced the understanding of plate tectonics and volcanic activity.
