Seismic data of the Earth has led to a model of the interior that partitions it into a core, mantle, and crust. The crust is approximately 30 kilometers thick. The mantle is approximately 2,840 kilometers thick, and the core radius is approximately 3,500 kilometers thick. Each partition can be further divided into smaller regions. The crust can be classified as oceanic or continental, the mantle as upper and lower, and the core as outer liquid and inner solid. Pictured in this cutaway view of the Earth is the crust, mantle, liquid outer core, and solid inner core. This image is Copyright © 1998 by Calvin J. Hamilton.
