Earth's inner core description
WebThe earth's inner core is approximately 1500 miles wide. It is estimated to be approximately 1,802 miles below the earth's surface (crust). Some scientists believe that the earth's inner core spins at a faster speed than the rest of it - at a rate of 2/3rds of a second faster. WebDec 13, 2024 · The Inner Core The inner core extends from the centre of the earth to 5100 km below the earth’s surface. The inner core is generally believed to be composed primarily of iron (80%) and some nickel ( nife ). Since this layer can transmit shear waves (transverse seismic waves), it is solid.
