Earth's interior is generally divided into three major layers: Other important data on the earth's interior come from geological observation of surface rocks and studies of the earth's motions in the solar system the planet earth is made up of three main shells:

The major layers are the crust, mantle and core. The internal structure of earth, structure of the solid earth, or simply structure of earth refers to concentric spherical layers subdividing the solid earth, i.e. The interior of earth can be observed through direct evidence such as rock samples from mining, deep ocean drilling project, volcanic eruptions and indirect evidence such as seismic waves, meteorite investigation, gravitation force, magnetic field etc.
Mechanically, it can be divided into lithosphere, asthenosphere, mesosphere, and.
Divisions in the earth's interior (adapted from, beatty, 1990.) seismic discontinuities aid in distinguishing divisions of the earth into inner core, outer core, d, lower mantle, transition region, upper mantle, and crust. Although this inner core is white hot, the pressure is so high the iron. Lying at the center of the earth is a solid core of extremely hot metals. The crust, the mantle, and the core.
