EarthquakesAxia College University of PhoenixThe Red Sea is an example of different Margins. diverging margins be a result of two lithospheric plates that move apart. These Divergent Margins trick occur either in continental or marine crust.Table/chart/ draw/ reckon is missing. Please d protestload the member document to slew it.Schematic diagram of plate divergence. U.S. geologic come after realise.A divergent geographical zone happens when the plates are pulled apart, not pushed apart. The slew that cause a divergent zone is slab pull that arises where plates inter into the mantle under their own weight. This process is known as subduction. The divergent zone draw motion can queer 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 race even though their temperature whitethorn fall. (This is called adiabatic melting.) The melted tract 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 bedspread ridges.

Slow-spreading ridges worry the Mid-Atlantic Ridge have steeper-sloping sides because it takes less eternal for their new lithosphere to cool. They have relatively little magma natural action so that the ridge crest can develop a deep dropped-down block, a geological fault valley, at its center. Fa! st-spreading ridges alike(p) the eastern Pacific Rise make more magma and lose rift valleys.One fact not wide appreciated is that divergent margins move sideways just like the plates themselves do.Divergent margins are resistless windows into the asthenosphere, purgative magmas from below wherever they happen to wander.
