Divergent Plate Boundary - OceanicWhen a divergent boundary occurs beneath oceanic lithosphere, the rising convection current below lifts the lithosphere, producing a mid-ocean ridge. Extensional forces stretch the lithosphere and produce a deep fissure. When the fissure opens, pressure is reduced on ...

Divergence is also going on in the Great Rift Valley of East Africa, forming the boundary between the Somalian and Nubian plates. But these rift zones, like the Red Sea, have not opened much even though they are millions of years old. Apparently, the tectonic forces around Africa are pushi...
Oceanic plates are denser and heavier. They are made of basaltic rocks. The ways that tectonic plates interact with each other are known as boundaries. There are three main types of boundaries: Convergent Divergent TransformWhat is a Convergent Boundary? Divergent Plate Boundaries What are T...
There are two types of divergent plate boundaries, namely continental-continental and oceanic-oceanic. Answer Key False, because the correct statement is: The constantly-evolving Himalayas is not an example of a divergent boundary. True False, because the correct statement is: Continental plates...
Globally most fault zones are located on divergent plate boundaries on oceanic crust. en.wikipedia.org Usually, only two arms of any given three-armed graben become part of a divergent plate boundary. en.wikipedia.org Volcanoes located at convergent plate boundaries emit more water vapor and chlor...
Key features of mid-oceanic ridges Divergent Plate Boundary:Mid-ocean ridges mark the boundaries between diverging tectonic plates. As the plates move away from each other, the upwelling of mantle material creates a long, continuous mountain range at the seafloor. ...
. With the exception of BIF, the observed sequence of basalt–chert–shale–BIF ± limestone is analogous to a typical Phanerozoic ocean plate lithostratigraphic assemblage recording migration of oceanic crust from the spreading ridge to the trench25. Within the Eastern Belt, this ocean plate ...
As this process continues, the activity causes a ridge in the seafloor. An example of an oceanic divergent boundary is the Mid-Atlantic Ridge. Iceland actually sits atop the Mid-Atlantic Ridge. Eventually, the island will be split into two separate landmasses because the plates will continue to...
