WebThe inner core’s surface seems to be rough and mushy at places, and its interior deformed by internal stresses. It might contain heterogeneity at various scales, and host another smaller shell more elusive to our seismological probes. Despite its small volume (less than 1% of the Earth's volume), the Earth's inner core contains about 10% of ...

9.2 The Temperature of Earth’s Interior – Physical Geology
WebThe earth’s inner core is a solid ball of iron, nickel and other metals, while the outer core is liquid metal composed of iron and nickel as well. The temperature of the inner core is estimated to be about 5,400 degrees C or 9,800 degrees F, far beyond iron’s melting point. Intense pressure present within the inner core prevents the iron ...
