Earths Structure And Layers Questions Medium
The inner core is the innermost layer of the Earth, located at the center. It is primarily composed of solid iron and nickel. The immense pressure at the Earth's core causes these materials to be in a solid state, despite the high temperatures. The inner core is approximately 1,220 kilometers (760 miles) in radius and is believed to have a temperature of around 5,000 to 6,000 degrees Celsius (9,000 to 11,000 degrees Fahrenheit).
