Is the mantle the asthenosphere
WitrynaThe asthenosphere is a plastic, solid layer of the mantle made of rock that flows very slowly and allows tectonic plates to move on top of it. Beneath the asthenosphere is the mesosphere, the lower part of the mantle Witryna6 lut 2024 · The asthenosphere is important for plate tectonics because it forms a relatively soft boundary that lets tectonic plates move through the mantle. The reasons why it is soft, however, are not...
