The diameter od mercurys core is 3,600 km, 2,235 miles.
No. The inner and outer core are both composed primarily of iron and nickel, but the outer core is liquid and surrounds the inner core. The inner core is the innermost layer of Earth and is kept solid by the enormous pressure.
the inner core is NOT made from rock.?!
the inner core is a solid
the solid inner core and the liquid outer core
The diameter od mercurys core is 3,600 km, 2,235 miles.
From the Earth's crust to the inner core is about 3,950 miles.
3160 miles-mantle to inner core.
== == Mercury has an iron-nickel core.
the anwer is that it is 3160 miles
Inner core
The inner core is predominately iron, with some nickel, and trace lighter elements, as far as we can deduce from current science.
The outer core is liquid, the inner core is solid The outer core surrounds the inner core The outer core is iron-rich, the inner core is iron-rich and nickel-rich There is more pressure acting on the inner core The inner core is hotter
To be precise, there is actually an outer core and an inner core. You can find the details in the Wikipedia article "Structure of the Earth".
The inner core.
The inner core
it is about 29 million kilometers apart
