The inner core is made from solid iron and nickel. In this diagram, the red lines represent ... The mantle is the thickest layer of the Earth and is made of semi-solid rock that moves very slowly ...

The Earth's interior is ... The deepest layer is a solid iron ball, about 1,500 miles (2,400 kilometers) in diameter. Although this inner core is white hot, the pressure is so high the iron ...

Earth's innermost layer is called the core. The outside of Earth's core is made from molten nickel and iron that can reach temperatures of 9,000 degrees Fahrenheit (5,000 degrees Celsius).

"The high-power laser is focused onto a multi-layered target, ablating the first layer ... both in the Earth's core or in other pressure-temperature regions of the iron phase diagram.

Researchers had long suspected the Earth had another layer at its core, but because its composition is so similar to the layer surrounding it, the innermost inner core was hard to spot.
