The inner core is 1216 km and made of solid iron. It is approx 5000 degrees C and it doesnt melt because of everything else pushing down on it.
the way in which the earths core spins is believed to be the source of its
The Core of Mars http:/en.wikipedia.org/wiki/Mars#Geology
The inner core has the most or highest amount of density (iron/nickel).
Inner core, which is also the innermost region of the Earth.
Earths outermost layer is the crust.Actually, the crust is divided into two parts,Sial and Sima.In that way, actually Sial is the outermost layer of the crust,as it lies above the Sima.
the inner part of earths core
The outer core is a liquid that is in between the inner core and mantle. It is 2,000km thick.
crust: average of 32 km thick mantle: 2900 km thick outer core: 2200 km thick inner core 1250 km thick
The radious of the inner core is 1,220km(760miles).
The outer core is thicker than the inner core. The outer core is about 2,260 kilometers thick, while the inner core is approximately 1,220 kilometers thick.
The inner core Is solid and the outer core in liquid
The outer core is 2900-5100 km thickThe inner core is 5100-6738 km thick
Yes earths inner core is a dense ball of metal earths outer core is a layer of molten (melted) metal
the crust is the thickness of earths layers
1220 km thick
