Iron–nickel alloy
- The characteristics of the core have been deduced mostly from measurements of seismic waves and Earth's magnetic field. The inner core is believed to be composed of an iron–nickel alloy with some other elements.

The inner core is believed to be composed of an iron–nickel alloy with some other elements. The temperature at its surface is estimated to be approximately 5,700 K (5,430 °C; 9,800 °F), about the temperature at the surface of the Sun. [5]
Jun 11, 2024 · The liquid outer core separates the inner core from the rest of Earth, and as a result, the inner core rotates a little differently than the rest of the planet. It rotates eastward, like the surface, but it’s a little faster, making an extra rotation about every 1,000 years.
Oct 10, 2014 · Earth's core is the deepest, hottest layer, and it's made up of two layers itself: the outer core which borders the mantle and the inner core, which is a ball-shaped layer made almost entirely of metal.
Aug 1, 2023 · The inner core is the central part of the Earth. It extends from a depth of about 5,150 km to the Earth’s center at about 6,371 km. Although it is very hot, the inner core is solid due to the immense pressure at this depth.
The Inner Core. It is the centre and the hottest layer of the Earth. The inner core is solid and made up of iron and nickel with temperatures up to 5,500oC. Due to its immense heat energy, the inner core is more like the engine room of the Earth.

- The inner core, the outer core, the mantle and the crust are the four layers of the earth.
- The Inner Core is the centre and the hottest layer of the Earth.
- The Outer Core comprises metals such as iron and nickel.
- The temperature of the Outer Core of the Earth is around 4000 o F to 9000 o F.
- Mantle is the widest section of the Earth. Its thickness is approximately 2,900 km.
Apr 30, 2023 · Earth is made up of several layers: the lithosphere, asthenosphere, lower mantle (also known as mesospheric mantle), outer core and inner core.
Oct 9, 2023 · The inner core is about 9,400 F (5,200 C) — about as hot as the surface of the sun — but tremendous pressure keeps it mostly solid. Inside the inner core is the innermost core, a...
