The Earth’s core has two parts: the outer core and the inner core. Both of these are made mainly of the metals iron and nickel. The outer core is liquid. But the inner core is a solid ball held in this liquid almost like the yolk(蛋黄) in an egg. ...

We show that such a scenario would prevent melt to flow out of the inner core. Since seismic observations do not show the presence of large amounts of liquid with depth, we argue that this is the first evidence to discard the possibility of a supercooling larger than 100K.#We calculate ...
Scientists first had a hunch that the inner core was moving in the 1990s, he said. It has taken years to back up that theory with hard evidence, mainly because of the difficulty of studying a mass located so far out of reach — and suspended inside a hellish sea of liquid...
core boundary. Similar content being viewed by others Multidecadal variation of the Earth’s inner-core rotation Introduction The oblate solid Earth consists mainly of a solid inner core, a liquid outer core, and a solid mantle with the same center of mass, which is reduced to a series of ...
Their inner life was so safe that they could bargain over externals in a way that would have been incredible to Aunt Juley, and impossible for Tibby or Charles. View in context Only by the inner purification of myself can I retain in some degree of purity the liquid I receive." View in...
