"Melting of rock at this depth is remarkable because most melting in the mantle occurs much shallower, in the upper 50 miles,"My admittedly simplistic understanding was that only Earth's crust is solid, with the remainder being molten or at least plastic, depending on depth. So why would melting at 'only' 400 miles be considered remarkable, when melting at 50 miles is not? Is it because most matter at this depth is only plastic and not molten, and is happening in these spots because of the presence of H2O, or some other reason?

"During the formation of the earth on the second and third days of creation, large quantities of water were evidently placed between the earth's crust and mantle in what might be called giant subterranean reservoirs. This water was probably under high pressure to begin with (causing artesian springs and geysers to abound"
So... you are saying earth's vast oceans and bodies of water came from comets?
It seems to me, and the researchers at Northwestern and Univ. New Mexico are saying otherwise.
