Divergent boundary lithosphere
At divergent boundaries, two plates move away from each other and the space that this creates is filled with new crustal material sourced from molten magma that forms below. The origin of new divergent boundaries at triple junctions is sometimes thought to be associated with the phenomenon known as hotspots. Here, exceedingly large convective cells bring very large quantities of hot asthenospheric material near the surface, and the kinetic energy is thought to b… WebJan 17, 2024 · At oceanic divergent boundaries, new lithosphere is born hot and cools over millions of years. As it cools it shrinks, thus the fresh seafloor stands higher than the older lithosphere on either side. This is …

The separating plates … WebMid-Oceanic Ridges. Figure 2.5.3. A divergent boundary may also form beneath the oceanic lithosphere, where mantle convection cells cause the plates to push apart and …
WebSep 17, 2024 · Divergent boundaries are where two of those plates are moving away from each other. When this happens, magma rushes up to fill the gap, creating brand new crust. Plates can be separated into two ... WebApr 14, 2024 · Most divergent boundaries are located along mid-ocean oceanic ridges (although some are on land).. Where is a divergent boundary on land? Divergent boundaries are typified in the oceanic lithosphere by the rifts of the oceanic ridge system, including the Mid-Atlantic Ridge and the East Pacific Rise, and in the continental …
Web2.3: Convergent Boundaries. Convergent boundaries, also called destructive boundaries, are places where two or more plates move toward each other. Convergent boundary movement is divided into two types, subduction and collision, depending on the density of the involved plates. Continental lithosphere is of lower density and thus more …
