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).
Where two tectonic plates converge, if one or both of the plates is oceanic lithosphere, a subduction zone will form. An oceanic plate will sink back into the mantle. Remember, oceanic plates are formed from mantle material at midocean ridges. Young oceanic lithosphere is hot and buoyant (low density) when it forms at a midocean ridge. But as it spreads away from the ridge and cools and contracts (becomse denser) it is able to sink into the hotter underlying mantle.
