Upper Mantlemantle
the upper mantle(lithosphere)and the lower mantle(mesosphere)
The asthenosphere lies in, and is the upper ductile part of, the mantle. It is the layer directly underneath the lithosphere; the layer composed of the crust and uppermost rigid mantle.
Since earth is not round but elliptical in shape, it's diameter at equator is 12,756km and it's diameter at poles is 12,712km.
It's mantle with less, then mantle with more as you go deeper into earth.
