Density of the crust
WebThe density of the layer is higher than the crust and varies from 3.3 – 5.4g/cm3. The uppermost solid part of the mantle and the entire crust constitute the Lithosphere . The asthenosphere (in between 80-200km) is a highly viscous, mechanically weak and ductile, deforming region of the upper mantle which lies just below the lithosphere. WebEarth consists of three main layers: the crust, the mantle, and the core (Figure 3.3). The core accounts for almost half of Earth’s radius, but it amounts to only 16.1% of Earth’s volume. Most of Earth’s volume (82.5%) is its mantle, and only a small fraction (1.4%) is its crust. Figure 3.3 Earth’s interior. Right- crust, mantle, and ...
