Sea floor spreading is a fundamental concept in plate tectonics that explains the formation and expansion of oceanic crust at mid-ocean ridges. The mechanism begins with the upwelling of magma from the mantle at divergent plate boundaries, primarily along mid-ocean ridges. As the hot mantle material rises, it partially melts due to decompression, forming basaltic magma. This magma intrudes into the existing oceanic crust and erupts onto the seafloor, cooling and solidifying to form new oceanic lithosphere. The continuous
