Hot, soft rock rise from the bottom of the mantle towards the top, cools, and sinks back through the mantle.
The mantle. Earth's layers are core, outer core, mantle.
The asthenosphere is made of soft rock and bends like plastic in the mantle.
The asthenosphere.
A portion of the upper mantle known as the asthenosphere.
The soft layer of rock in the Earth's mantle is called the asthenoshere. The asthenoshere is a solid but able to flow slowly.
Hot, soft rock rise from the bottom of the mantle towards the top, cools, and sinks back through the mantle.
Working outwards from the centre: The Earth is believed to be formed of an inner core, outer core, inner mantle, outer mantle, and the crust. The mantle is two thousand miles thick and makes up more than three-quarters of the Earth's volume.

No, crustal rock is cold, hard, and brittle while mantle rock is hot, soft, and plastic. Crustal rock fractures under stress while mantle rock deforms and slowly flows under stress.
Clay, typically, is the only soft and plastic rock. Unless you were thinking of the Mantle, which forms the bulk of the planet Earth. It is hot enough to be "molten" although in fact is extremely viscous.
The mantle. Earth's layers are core, outer core, mantle.
Rocks in the lower mantle are hot and soft (but not molten). The lower mantle flows slowly, at a rate of a few centimeters per year.
The asthenosphere is made of soft rock and bends like plastic in the mantle.
The asthenosphere.
As the question uses the word mantle which is a compositional layer of the earth, then the answer is crust.
