Earth's inner core is the innermost geologic layer of the planet Earth. It is primarily a solid ball with a radius of about 1,220 km (760 mi), which is about 20% of Earth’s radius or 70% of the Moon's radius. There are no samples of Earth's core accessible for direct measurement, as there are for Earth's mantle.
Jun 11, 2024 · Inner Core. The inner core is a hot, dense ball of (mostly) iron. It has a radius of about 1,220 kilometers (758 miles). Temperature in the inner core is about 5,200° Celsius (9,392° Fahrenheit). The pressure is nearly 3.6 million atmospheres (atm). The temperature of the inner core is far above the melting point of iron.
Nov 21, 2023 · The inner core is the innermost layer of the Earth. It helps generate the Earth's magnetic field through interactions with the outer core. It is also slowly growing (1 mm/yr.) as the...

May 7, 2024 · More than 5,000 kilometres beneath the surface is Earth’s inner core, a solid metallic ball, slightly smaller than the moon, that sits at the centre of our planet. Think of it as a time capsule – a fossilised record that takes us back into the deep past and tells us more about the planet’s evolution. Not only can the inner core enlighten ...
The core accounts for almost half of Earth’s radius, but it amounts to only 16.1% of Earth’s volume. Most of Earth’s volume (82.5%) is its mantle, and only a small fraction (1.4%) is its crust. Figure 3.4 Earth’s interior. Right- crust, mantle, and outer and inner core to scale.

The structure of the earth is divided into four major components: the crust, the mantle, the outer core, and the inner core. Each layer has a unique chemical composition, physical state, and can impact life on Earth's surface.
Inside the Earth. The Earth's interior is composed of four layers, three solid and one liquid—not magma but molten metal, nearly as hot as the surface of the sun. The deepest layer is a solid iron...
