WebThe structure of the earth is divided into four major components: the crust, the mantle, the outer core, and the inner core. Each layer has a unique chemical composition, physical state, and can impact life on Earth's surface. WebThe inner core is the fourth layer inside the Earth. It is a solid metallic ball made mainly of iron. Here, temperatures reach extraordinary levels, estimated to be between 7,200–8,500ºF (4,000–4,700ºC).

"Earth's inner core is the innermost geologic layer of planet Earth. It is primarily a solid ball with a radius of about 1,220 km (760 mi), which is about 20% of Earth's radius or 70% of the Moon's radius. There are no samples of Earth's core accessible for direct measurement, as there are for Earth's mantle. … See more Earth was discovered to have a solid inner core distinct from its molten outer core in 1936, by the Danish seismologist Inge Lehmann, who deduced its presence by studying seismograms from earthquakes in See more Seismic wave velocity The velocity of the S waves in the core varies smoothly from about 3.7 km/s at the center to about 3.5 … See more Many scientists had initially expected that the inner core would be found to be homogeneous, because that same process should … See more Because the inner core is not rigidly connected to the Earth's solid mantle, the possibility that it rotates slightly more quickly or slowly than the rest of Earth has long been entertained. In the 1990s, seismologists made various claims about detecting See more Seismic waves Almost all direct measurements that scientists have about the physical properties of the … See more There is still no direct evidence about the composition of the inner core.
