Mechanical layering of the earth: - Lithosphere (solid/rigid), 0-150km - Asthenosphere (solid/elastic), 150-660km - Mantle (solid/rigid), 660- 2900km - Outer core (liquid), 2900-5730km - Inner core, 5730-6400km Chemical layering of the earth: - Crust (oceanic and continental), 0-40km - Mantle, 40-2900km - Core, 2900-6400km
The Earth's compositional layers in order of increasing density are the crust, mantle, outer core, and inner core. The crust is the least dense layer, while the inner core is the most dense layer.
There are generally four main compositional layers in the Earth: the crust, mantle, outer core, and inner core. These layers differ in their composition, temperature, and physical properties, and they play a crucial role in shaping the Earth's structure and dynamics.
The Earth's crust is the thinnest compositional layer, ranging from 5 to 70 kilometers thick beneath the oceanic crust and up to 100 kilometers thick beneath continents.
The Earth is typically divided into four layers: the crust, mantle, outer core, and inner core. These layers have different compositions and physical properties, and they play important roles in shaping the planet's structure and behavior.
