Is seafloor spreading happening, because Morton material beneath earths crust rises to the surface

Answer 1

Seafloor spreading is not directly caused by Morton material rising to the surface beneath the Earth's crust.

Seafloor spreading is a geologic process occurring at mid-oceanic ridges, where new oceanic crust is formed. It is driven by the movement of tectonic plates. The Earth's crust is made up of several large tectonic plates that are constantly moving. At the mid-oceanic ridges, molten material called magma rises from the mantle and fills the gap between the separating tectonic plates. This magma solidifies and forms new crust, pushing the older crust apart.

The rising of magma from the mantle is not specifically associated with Morton material, but rather with the incomplete melting of the upper mantle. The mantle beneath the Earth's crust is mostly composed of solid rock, and when it partially melts, it forms magma, which then rises to the surface at mid-oceanic ridges during seafloor spreading.

In summary, seafloor spreading is primarily driven by the movement of tectonic plates and the upwelling of magma from the mantle, not specifically by Morton material rising to the surface.
