WebThe portion of the interior beyond the crust is called the mantle. It is in a solid-state. It has a density higher than the crust portion. The thickness ranges from 10-200 km. The mantle extends from Moho’s discontinuity to a depth of 2,900 km. The asthenosphere is the upper portion of Mantle. WebOceanic crust tends to be thinner and denser than continental crust.
