The core of the Earth, which has both liquid and solid layers, and consists mostly of iron, nickel, and possibly some oxygen [ 31 ]. Scientists looking at seismic data first discovered this innermost chemical layer in 1906 [ 32 ].
WebInner Core: This is the deepest part of the earth, made up of solid iron and nickel. The inner core creates the earth's magnetic field which helps protect the earth from harmful radiation from the sun. The lithosphere is the solid, hard layer that makes up the earth's crust, consisting of rocks, minerals, and soil.
Recent estimates (2007) allow for up to 10% nickel and 2–3% of unidentified lighter elements. According to computations by D. Alfè and others, the liquid outer core contains 8–13% of oxygen, but as the iron crystallizes out to form the inner core the oxygen is mostly left in the liquid. See more Earth's inner core is the innermost geologic layer of planet Earth.

According to … 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 New Zealand. She observed that the seismic waves … 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 km/s at the surface. That is … See more Many scientists had initially expected that the inner core would be found to be homogeneous, because that same process should have proceeded uniformly during its entire formation. It was even suggested that Earth's inner core might be a See more
