In plate tectonics, a divergent boundary or divergent plate boundary (also known as a constructive boundary or an extensional boundary) is a linear feature that exists between two tectonic plates that are moving away from each other.
Apr 24, 2024 · Divergent Plate Boundaries. A divergent plate boundary is when two plates move away from each other under tensional stress. The oceanic crust becomes thin, and cracks open up fissures. Magma moves up to the surface through these fissures and solidifies, creating new oceanic crust.
Divergent boundaries are spreading boundaries, where new oceanic crust is created to fill in the space as the plates move apart. Most divergent boundaries are located along mid-ocean oceanic ridges (although some are on land).
Learn how the Earth's lithosphere is made of moving tectonic plates that form three types of boundaries: divergent, convergent, and transform. Divergent boundaries occur when two plates move apart, creating new oceanic crust, while convergent boundaries occur when two plates collide, creating mountains, volcanoes, and deep trenches.
Feb 15, 2021 · 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.
