KIDS TRIVIA

Detailed explanation-1: -Unlike the mineral-rich crust and mantle, the core is made almost entirely of metal-specifically, iron and nickel. The shorthand used for the core’s iron-nickel alloys is simply the elements’ chemical symbols-NiFe. Elements that dissolve in iron, called siderophiles, are also found in the core.

Detailed explanation-2: -Iron, nickel, and other heavy metals like gold, are what makes up the core of the earth because they are the heaviest of the metals and so sank toward the center of the earth.

Detailed explanation-3: -Earth’s core consists of a solid iron-nickel ball rotating within a layer of liquid metal.

Detailed explanation-4: -Inner core At the very center of the Earth is a white-hot core of solid iron and nickel. It is hot enough for the metals to melt into a liquid, but they stay solid because they are squeezed together by the weight of rock on top.

Detailed explanation-5: -Inner core: This is the central layer of Earth. It has the maximum temperature. This layer is made up of nickel-iron alloy. Thus, the inner core is made up of nickel and iron alloy.
