Quizplus · Accepted Answer

The asthenosphere is a warm and ductile layer of the Earth's mantle that underlies the rigid lithosphere. This is due to the fact that the asthenosphere is closer to the Earth's core, where temperatures and pressures are higher, causing the rock to be more ductile and less rigid than the cooler lithosphere.
