Web25 apr. 2024 · 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 magma has created high ridges on the ocean floor over millions of years. However, the seafloor is destroyed in … Web23 jul. 2024 · Seafloor spreading occurs at divergent plate boundaries. As tectonic plates slowly move away from each other heat from the mantle’s convection currents makes the crust more plastic and less dense. The less-dense material rises often forming a mountain or elevated area of the seafloor. side effect of gluta drip
