Why does divergent plate boundaries create new ocean crust?

Divergent plate boundaries occur where tectonic plates move apart from each other, allowing magma from the mantle to rise to the surface. As this magma cools and solidifies, it forms new oceanic crust. This process typically occurs along mid-ocean ridges, where the continuous upwelling of magma results in the creation of new seafloor as the plates separate. Consequently, divergent boundaries are essential for the renewal and expansion of oceanic crust.
