1. Structure of the Earth First Bilingual

3. Structure of the Earth The structure of the Earth can be defined in two ways: Chemically, or by mechanical properties: Chemically, the interior of the earth is divided into 3 important layers, divided into the crust, mantle, and core. The geologic component layers of Earth are at the following depths below the surface. Mechanically, it can be divided into lithosphere, asthenosphere, mesosphere, outer core, and the inner core

4. The liquid outer core, magma, surrounds the inner core The Earth's mantle extends to a depth of 2890 km, making it the thickest layer of the Earth.Earth's mantle The crust ranges from 5 to 70 km in depth and is the outermost layer: The thin parts are the oceanic crust.oceanic crust The thicker crust is continental crust.continental crust
