The interior of the earth

January 1, 1989

The center of the Earth lies nearly 4,000 miles beneath our feet. At present the nature of the Earth's interior is known only from indirect evidence collected from studies of rocks and minerals, seismic waves, heat flow from the interior, and the Earth's gravity and magnetic field and through comparisons of the Earth with other planets, with meteorites, and with the Sun and other stars.
