what is the density of the inner core and what is it made out of so they say?

Answer 1

The inner core is not well understood. What we do know comes from observations of the behavior of seismic waves that have traveled through the core and from a comparison of elemental abundances in the solar system and the Earth. The inner core is believed to be predominantly iron, with some nickel and a few lighter elements (top candidates are probably oxygen and sulfer). It's density is believed to be slightly less than the density of iron which is 7.86 gm/cm3. (Nickel has a density of 8.908 gm/cm3, so if nickel is present we believe some lighter elements must be present as well). Yes, it gets a bit circular but since we can't exactly go snag a sample we work with what we have. Here are some good sites if you're really curious:

Answer 2

The inane questions and a few of the solutions point out that folk frequently have have been given little seen the actual nature of the image voltaic gadget. maximum folk might have wide-unfold just about no longer something approximately Pluto, different than that it shared its call with a Disney sketch character. So, why is all and sundry so disillusioned. it relatively is relatively a shaggy dog tale. It aint a planet. If it remained a planet, we'd ought to start calling 1000's, consistent with possibility 1000's of different gadgets planets, as they are got here across interior the outer areas of the planetary gadget. For goodness sake improve up all and sundry. you're so dammed juvenile.

Answer 3

I believe it is molten elements fueled by nuclear reaction like the sun. The crust floats on this core. Heavy water (deuterium) H2O2 is a by product of nuclear reactions. It is found in the sea. Its half life is not very long. So it must be renewing all the time with lava seepage in certain ares of the ocean bottom.

Answer 4

It is made of Nickel and iron and it density is hard because of the pressure
