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.
Jan 17, 2020 · Andrew Alden. Updated on January 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.
Mar 7, 2024 · For example, sections of Earth’s crust can come together and collide (a “convergent” plate boundary), spread apart (a “divergent” plate boundary), or slide past one another (a “transform” plate boundary). Each of these types of plate boundaries is associated with different geological features.
Feb 11, 2020 · The landscapes of several National Park Service sites reveal divergent plate boundary processes that have resulted in continental rift zones and passive continental margins. Shaded relief map of United States, highlighting National Park Service lands at Divergent Plate Boundaries.
There are four types of plate boundaries: Divergent boundaries -- where new crust is generated as the plates pull away from each other. Convergent boundaries -- where crust is destroyed as one plate dives under another. Transform boundaries -- where crust is neither produced nor destroyed as the plates slide horizontally past each other.
And in particular, I want to focus on the features we see at divergent plate boundaries, where the plates are moving away from each other, or where new land is being created like we saw in the mid-oceanic ridges, where we see new land being created right in the center and moving outwards from them.
