A 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. The Mid-Atlantic Ridge is an example of divergent plate boundaries.
At divergent boundaries, sometimes called constructive boundaries, lithospheric plates move away from each other. There are two types of divergent boundaries, categorized by where they occur: continental rift zones and mid-ocean ridges. Continental rift zones occur in weak spots in the continental lithospheric plate.
Apr 24, 2024 · A divergent plate boundary under water is called a mid-ocean ridge, such as the mid-Atlantic ridge. Check out the eastern half of Africa and notice the lakes that look linear. Eastern Africa is separated from these linear lakes by the Great Rift Valley and the Red Sea. Notice how the Red Sea looks like it could be put back together again.
Feb 15, 2021 · Divergent Plate Boundaries. Divergent plate boundaries are locations where tensional forces are pulling things apart. In locations where lithospheric plates are diverging, the rates of divergent motion range from 2 to 17 cm/year. Spreading Centers along Divergent Plate Boundaries.
Jan 17, 2020 · Divergent boundaries exist where tectonic plates move apart from each other. Unlike convergent boundaries, divergence occurs between only oceanic or only continental plates, not one of each. The vast majority of divergent boundaries are found in the ocean, where they were not mapped or understood until the mid-to-late 20th century.

Mar 7, 2024 · National Geographic MapMaker: Plate Boundaries. In some ways, Earth resembles a giant jigsaw puzzle. That is because its outer surface is composed of about 20 tectonic plates, enormous sections of Earth’s crust that roughly fit together and meet at places called plate boundaries. Plate boundaries are important because they are often ...
