EarthquakesAxia College University of PhoenixThe Red Sea is an example of divergent Margins. diverging margins ar a result of two lithospheric plates that move apart. These Divergent Margins slew occur either in continental or oceanic crust.Table/chart/ draw/ reckon is missing. Please d protestload the rule book document to slew it.Schematic diagram of plate divergence. U.S. geologic keep up get wind.A divergent geographical zone happens when the plates are pulled apart, not pushed apart. The serving that cause a divergent zone is slab pull that arises where plates fade into the mantle under their own weight. This process is known as subduction. The divergent zone draw motion can uncover the duncish mantle flap of the asthenosphere. Table/chart/diagram/image is missing. Please download the Word document to view it.As the pressure eases on the deep rocks, they begin to partially work even though their temperature whitethorn fall. (This is called adiabatic melting.) The melted packet expands (as melted solids generally do) and rises, having nowhere else it can go. This magma then freezes onto the trailing edges of the diverging plates, and so the plates grow.http://geology.about.com/library/bl/blnutshell_divergence.htm Says Lithospheric Plates diverge at a wide range of speeds, giving rise to differences in spread ridges. Slow-spreading ridges worry the Mid-Atlantic Ridge have steeper-sloping sides because it takes less quad for their new lithosphere to cool. They have relatively little magma accomplishment so that the ridge crest can develop a deep dropped-down block, a geological fault valley, at its center. Fast-spreading ridges identical the eastern Pacific Rise make more magma and leave out rift valleys.One fact not wide appreciated is that divergent margins move sideways just like the plates themselves do.Divergent margins are unresisting windows into the asthenosphere, purgative magmas from below wherever they happen to wa nder.
