Divergent boundary cause seafloor spreading

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 … WebA divergent boundary is an area where two crustal plates are separating. Most of these tectonic plate boundaries are located on the floor of the oceans. The separating plates …
