Evidence points to “iron snow” falling on Earth’s inner core

A team of geologists from China and the US have found evidence to suggest that snow may be falling within the broiling hot core of planet Earth. Of course, this isn’t your everyday surface snow – the researchers say that these flakes would be made of iron alloys, gently settling down onto the solid inner core through the more fluid outer core.

>>>the inner core is far younger than the rest of the planet.

Maybe the collision which created the moon is other planets core?

Perhaps the results are in error?

Or there is a process going on that been missed that making the core look younger?

If 2 objects crash into each other, is it possible that one of the objects ejects its core ? the smaller of the 2 or the less dense of the 2 ?

if one the objects had a less developed core being less dense it could have been pushed out by a denser core.

something like that

They mean that the inner core didn’t solidify until relatively recently:

ok, so with convention going on particles are settling down through that convection ?

and the core is slowly getting bigger that way.

but all those iron particles have the same age, so there’s something I’m not understanding.

How do the iron particles go from being older to younger?

Yep. “Heat is work and work’s a curse, and all the heat in the universe is going to cool down, cause it can’t increase”. As the Earth cools (radioactive decay) the inner solid core grows and the outer liquid core shrinks. The mantle and crust shrinks, too.

Huh? They go from being liquid (not particles) in the outer core to being solid on the surface of the inner core.
