Lina Hardin · Answer 2

Answer: The iron-nickel alloy melts due to hot temperatures.

Explanation:

Earth's outer core is composed of fluid layer that is about 2400 km thick and primarily composed of iron and nickel alloy. It lies above the solid inner core and below the mantle. The core of the earth is like a furnace. It exhibit intense heat and pressure which keeps the iron-nickel alloy in the molten state in the core region.
