WebPicture two giant conveyor belts, facing each other but slowly moving in opposite directions as they transport newly formed oceanic crust away from the ridge crest. Perhaps the best known of the divergent boundaries is the Mid-Atlantic Ridge. This submerged mountain range, which extends from the Arctic Ocean to beyond the southern tip of Africa ... WebThe "triple junction" is an important part of the global plate movement system. The expanding Chilean ridge subducted into the South American plate to form the Chile triple junction and caused drastic topographical changes within a few hundred kilometers in the south of the Chile triple junction. The differences in factors such as the initial angle of …

The oceanic lithosphere is formed at an oceanic ridge, while the lithosphere is subducted back into the asthenosphere at ocean trenches. Two processes, ridge-push and slab pull, are thought to be responsible for spreading at mid-ocean ridges. Ridge push refers to the gravitation sliding of the ocean plate that is raised above the hotter asthenosphere, thus creating a body force causing sliding of the plate downslope. In slab pull the weight of a tectonic plate being subducted (pulled… halle hilton

WebApr 26, 2024 · Mid oceanic ridge formation. It occurs along the divergent plant boundaries when a new floor is formed, due to earth tectonic plates spread apart, also called seafloor spreading. In the volcanic eruption, molten basalt comes out. The speed of spreading of molten basalt affects the shape of the ridge. Faster spreading produces wider and more ...
