Earth's inner core is solid due to the exceptionally high pressure (approximately 330 to 360 GPa) which drives up the melting point of iron beyond the temperatures found within the inner core.
immense pressure
it remains solid because of all the pressure. Also, it is solid because it is the inner core
The immense pressure from the layers outside of the inner core.
The outer portion of the core is mostly molten iron. The inner core is solid metal.
The mantle! I remember learning this in geography :)
An alloy of solid nickel and iron, mostly.
it remains solid because of all the pressure. Also, it is solid because it is the inner core
the earths core is the hottest part of the earth. the metals in the earths outer core is liquid because of the heat and the metals in the earths core is solid but still the earths core is the hottest
The inner core Is solid and the outer core in liquid
The solid inner and liquid outer core.
The immense pressure from the layers outside of the inner core.
a solid ball of iron
Yes the refraction path of the p-wave tells us that the earths inner core is solid.
the inner core
iron and nickel is the answer and so is the inner core. the inner and the outer and together but the outer core is liquid and the inner core is solid
Both! The outer core is in a liquid state and the inner core is a solid. Both the inner and outer core are formed mainly of iron and nickel.
the outer core is liquid; the inner core is solid
The earth's inner core is 3160 kilometers beneath the earths surface. The inner core is a solid ball of nickel-iron alloy.
