WebAs the plates move apart (very slowly), magma rises from the mantle to fill the gap. This is also accompanied by earthquakes. When the magma reaches the surface, it cools and solidifies to form a... WebThe Mid-Atlantic Ridge runs down the center of the Atlantic Ocean, slowly spreading at a rate of 2 to 5 centimeters (0.8 to 2 inches) per year and forming a rift valley that is about the depth and width of the Grand …
WebMost divergent plate boundaries are underwater and form submarine mountain ranges called oceanic spreading ridges. While the process of forming these mountain ranges is volcanic, volcanoes and earthquakes … WebThe Ridge is a high area compared to the surrounding seafloor because of the lift from the convection current below. A frequent misconception is that the Ridge is a build-up of volcanic materials; however, the magma that fills the fissure does not flood extensively over the ocean floor and stack up to form a topographic high. Instead, it fills ...
