Mantle (geology) The mantle is a layer inside a terrestrial planet and some other rocky planetary bodies. For a mantle to form, the planetary body must be large enough to have undergone the process of planetary differentiation by density.
asthenosphere. n. 1. (Geological Science) a thin semifluid layer of the earth (100-200 km thick), below the outer rigid lithosphere, forming part of the mantle and thought to be able to flow vertically and horizontally, enabling sections of lithosphere to subside, rise, and undergo lateral movement.See also isostasy.he upper part of the Earth's mantle. The asthenosphere lies beneath the lithosphere and consists of several hundred miles of partially molten rock. Because it is partially molten, seismic waves passing through this layer have slow velocities.
