While the hot spot itself is fixed, the plate is moving. So, as the plate moved over the hot spot, the string of islands that make up the Hawaiian Island chain were formed. WebIn the 1 950’s and 1960’s, scientists discovered seafloor spreading, where new crust is formed at mid-ocean ridges, and formulated the theory of plate tectonics. The basic …
