the issue is, if we think that is liquid (at least partially) being composed of two metals. To explain the liquidity of the Earth's core, it is necessary to include additional items that the density data collected by earthquakes (the propagation of seismic waves

is the technique used for) us have revealed are sulfur and oxygen.

terrestrial dynamics as seen by the GeoForschungsZentrum Potsdam (GFZ) --- Well, where is all this leading? The obvious question we ask here, and has recently been the core of the sci-FICCNucleus

ion (forgive the redundancy), is ... will spin forever? Here is where you should speculate. The answer, contrary to what may seem, it is not obvious, since there are geological deposits that demonstrate that the periodic magnetic pole reversal suffered by the Earth is slowing down (the last , which could be living, it comes with 250000 years late) due to the crystallization Earth's core.
But you tell me? Well, to answer
an example: Mars . As our twin brother, has no magnetic field whatsoever & eacute; tico that protects us from dangerous solar flares and cosmic ray heavy rain that could end life on earth as we know, and that in the past (3 million years, according to the latest estimates) could, to disappear, ending life on Mars .

Without entering into controversy about the last sentence (and talk about that in another post) is a fact that the Earth is larger than Mars, and therefore to be expected that their numbers nucleus is larger and remains liquid longer, either because of its higher sulfur content, either by the increased pressure quand holds the stuff that's about it.
I do not want to extend a lot, so I stand.
By the way, a new one every Friday or so, so that you have to do chat with the beer of the weekend.
