First step in the seafloor spreading process
WebApr 25, 2024 · The seafloor spreading hypothesis was proposed by the American geophysicist Harry H. Hess in 1960. Seafloor spreading is the process of magma welling up in the rift as the old crust pulls itself in opposite directions. Cold seawater cools the magma, creating a new crust. The upward movement and eventual cooling of this … WebFeb 22, 2010 · Who invented seafloor spreading? A man by the name of Harry Hess invented seafloor spreading.

As heated it rises in the crust (divergent boundary) commonly it rises in a divergent boundary. As it rises magma flows out and create new seafloor. Then the old seafloor was pushed in a convergent boundary to subduct in the mantle and burns. As known it repeats itself again and again. high credit extended meaning
