The Earth's inner core is composed mainly of iron and nickel in a solid state due to high pressure and temperature. Therefore, the Earth's inner core would be best modeled as a metallic sphere.
The core.
The inner core is the layer closest to the Earth's center, located beneath the outer core and mantle. It is a solid metallic sphere composed mainly of iron and nickel.
The inner core of the Earth is a solid metallic sphere made primarily of iron and nickel with a radius of about 1216 kilometers. It is surrounded by the liquid outer core and the solid mantle.
The ancient Greeks were the first culture to determine that the Earth was a sphere. Philosophers such as Pythagoras and Aristotle provided evidence through observations and reasoning that supported this belief.
The sphere that extends from Earth's core to Earth's crust is known as the mantle. It is a layer of solid rock that lies between the core and the crust, making up the majority of Earth's volume. The mantle is divided into the upper mantle and the lower mantle based on depth and composition.
