How the rock flows in the asthenosphere
NettetAs a result, seismic waves slow as they enter the asthenosphere. With increasing depth, however, the greater pressure from the weight of the rocks above causes the mantle to become gradually stronger, and … NettetRocks. They form within the Earth and make up a large part of our planet. Rocks are so common that most of us take them for granted—cursing when we hit them with the …

Nettet15. apr. 2024 · Starting at around 80 to 100 km deep, the rock in the asthenosphere slowly flows in a plastic state moving in a circular motion creating convection currents of hot rock. This moves heat from deep within the mantle towards the surface. Is the mantle asthenosphere solid or liquid? Nettet23. aug. 2024 · Rocks in the asthenosphere are “plastic”, meaning that they can flow in response to deformation. Even though it can flow, the asthenosphere is still made of solid (not liquid) rock; you can think of it kind of like Silly Putty. What determines whether rocks act in a rigid manner (bending or breaking) or a plastic manner (flowing) is temperature.
