2025年11月10日 · Learn about the structure of the Earth, its crust, mantle, and core. Discover how heat, pressure, and convection shape our dynamic planet from within.

The primary structure is a series of layers: an outer silicate crust, a mechanically weak asthenosphere, a solid mantle, a liquid outer core whose flow generates the Earth's magnetic field, and a solid inner core.

Structure of the Earth - Find out how the Earth is structured, the features of each section and the characteristics of the crust (lithosphere).

The structure of the earth is divided into four major components: the crust, the mantle, the outer core, and the inner core. Each layer has a unique chemical composition, physical state, and can impact life …
