Internal structure of Earth - Wikipedia
The internal structure of Earth are the layers of the Earth, excluding its atmosphere and hydrosphere. The structure consists of an outer silicate solid crust, a highly viscous asthenosphere, and solid mantle, a liquid outer core whose flow generates the Earth's magnetic field, and a solid inner core.

Structure of the Earth - Internet Geography
Structure of the Earth. When studying plate tectonics, the best starting point is examining the structure of the Earth. The Earth is divided into a series of layers: the inner core, outer core, mantle and crust. Each of these layers has its own chemical and mechanical properties.
Structure of the Earth - Simple English Wikipedia, the free …
The structure of the Earth is divided into layers. These layers are both physically and chemically different. The Earth has an outer solid layer called the crust, a highly viscous layer called the mantle, a liquid layer that is the outer part of the core, called the outer core, and a solid center called the inner core.
