Hillary received 19 delegates while Bernie only received 15, but Bernie received just less than 5% fewer votes than Hillary. Wouldn't it make sense if Hillary received 18 and Bernie 17? (There should be 35 delegates in Nevada so one wasn't placed yet I think)
(For reasons discussed later in this chapter, new oceanic lithosphere at a mid-ocean ridge is much thinner.) Recall that the crustal part of continental lithosphere ranges from 25 to 70 km thick and consists largely of low-density felsic and intermediate rock. In contrast, the crustal part of oceanic lithosphere is only 7 to 10 km thick and consists largely of relatively high-density maï¬c rock (basalt and gabbro). The mantle part of both continental and oceanic lithosphere consists of very high-density ultramaï¬c rock (peridotite).
Stable subduction zones involve the oceanic lithosphere of one plate sliding beneath the continental lithosphere or oceanic lithosphere of another plate due to the higher density of the oceanic lithosphere.That is, the subducted lithosphere is always oceanic while the over-riding lithosphere may or may not be oceanic. Subduction Zone Physics: Sinking of the oceanic lithosphere (sediments + crust + mantle), by contrast of density between the cold and old lithosphere and the hot asthenospheric mantle wedge, is the strongest force (but not the only one) needed to drive plate motion and is the dominant mode of mantle convection.
