Earth's inner core is the innermost geologic layer of the planet earth. it is primarily a solid ball with a radius of about 1,220 km (760 mi), which is about 19% of earth's radius [0.7% of volume] or 70% of the moon 's radius. [ 32][ 33] the inner core was discovered in 1936 by inge lehmann and is generally composed primarily of iron and some. The outer core extends from 2,900 km to about 5,150 km beneath the earth’s surface. it mainly consists of liquid iron and nickel. the motion within this layer generates the earth’s magnetic field. the inner core. the inner core is the central part of the earth. it extends from a depth of about 5,150 km to the earth’s center at about 6,371 km.

Starting at the center, earth is composed of four distinct layers. they are, from deepest to shallowest, the inner core, the outer core, the mantle and the crust. except for the crust, no one has ever explored these layers in person. in fact, the deepest humans have ever drilled is just over 12 kilometers (7.6 miles). The core is divided into a solid inner core and a liquid outer core. the outer core is around 2200 km thick, and the inner core is 1,230 to 1,530 km thick. all three layers of the earth are easily distinguishable in layers of the earth 3d model. it is composed mainly of nickel (ni) and iron (fe). hence it is called nife.

Earth consists of three main layers: the crust, the mantle, and the core (figure 3.4). the core accounts for almost half of earth’s radius, but it amounts to only 16.1% of earth’s volume. most of earth’s volume (82.5%) is its mantle, and only a small fraction (1.4%) is its crust. figure 3.4 earth’s interior. right crust, mantle, and.
