Witryna12 maj 2011 · Fig. 4 The internal structure of Io as revealed by the present study. Underneath a low-density crust 30 to 50 km thick (gray outline in the cross section) exists a global magma layer (asthenosphere) with a thickness exceeding 50 km and a rock melt fraction of a few tens of percent (red-brown outline). Witryna15 sty 2001 · As the two plates separate, the mantle rock from the asthenosphere layer below flows up into the void between the plates. Because the pressure is not as great at this level, the mantle rock will …
