The iron-nickel alloy melts due to hot temperatures.
Explanation: Temperatures in the outer core are high enough to melt the iron-nickel alloy there — they overcome the pressure at that depth, producing a liquid outer core. (By contrast, the inner core is solid because pressure is even higher and forces the metal into a solid state.)
