Earth's inner core is the innermost geologic layer of the Earth. It is primarily a solid ball with a radius of about 1,220 kilometres (760 miles), which is about 20% of the Earth's radius and 70% of the Moon's radius. There are no samples of the Earth’s core available for direct measurement, as there are for the Earth's mantle.
Below it are the outer core and inner core of the Earth, making up about 29% of the Earth's volume, and composed primarily of molten (outer core) or solid (inner core) iron and nickel. Ad. The upper mantle (aesthenosphere) has a low density relative to the rest of this layer, and flows fluidly, like a plastic. Conditions gets hotter and denser ...
In terms of consistency, geologists believe the core is largely made up of iron and nickel, as well as lighter elements such as sulfur, oxygen and silicon. New insight into extra-terrestrial life . For Tkalčić, the findings offer a unique chance to “track the evolution of the inner core back in time" and estimate the age of the Earth.

But scientists studying the formation of Earth’s core have shown that the lightweight nonmetal might also be present there in vast quantities, answering a question that has long troubled earth scientists: How could Earth’s core—predominantly made of the heavy elements iron and nickel—appear as light as it does when analyzed using ...

The third element of the earth's interior is composed of huge currents that carry heat from the core through the mantle up to the crust. These currents of melted rock, or magma, flow to the surface and erupt through vents called volcanoes.
