WebNov 7, 2024 · An oceanic divergent boundary is a type of tectonic boundary where two plates are moving apart from each other. This type of boundary is found under the ocean, where magma from the mantle rises up and creates new crust. As the magma cools, it solidifies and becomes part of the earth's crust. This process is known as sea-floor … WebA divergent boundary occurs when two tectonic plates move away from each other. Along these boundaries, earthquakes are common and magma (molten rock) rises from the Earth’s mantle to the surface, solidifying to create new oceanic crust. 2. what type of plate boundaries exist in the following plate Explanation:

WebEarthquakes are pretty common along divergent boundaries. They frequently happen on the mid-Atlantic ridge and East Pacific rise. These earthquakes are characteristically restricted. They happen close to the ridge and are consistently at a depth of fewer than 30 km. Types Of Divergent Plate Boundaries 1. Divergent Plate Boundary – Oceanic WebThe Mid-Atlantic Ridge was the first example of a Mid-Ocean Ridge discovered by scientists, and is 16,000 km (10,000 miles) long. Divergent boundaries are sites of magma upwelling from the mantle because the tensional stress has thinned the lithosphere enough to allow the molten plume to penetrate the surface. Figure 2.8.5. WebWhen a convergent boundary occurs between two oceanic plates, one of those plates will subduct beneath the other. Normally the older plate will subduct because of its higher density. The subducting plate is heated as it is forced deeper into the mantle, and at a depth of about 100 miles (150 km) the plate begins to melt. business process header data table
