Earth's Primordial Differentiation, and Its After-effects
Abstract
The case for massive primordial melting on the Earth is circumstantial (i.e., based mainly on lunar evidence), but nonetheless compelling. The term magma ocean is probably a hyperbole. Among other things, ocean implies the system is virtually 100% liquid, with a mainly gas/liquid upper surface, and a water like viscosity of the order .01 poise. The preferred term for this phenomenon is magmasphere.
