The crust which consists of rocks rich in silica has a density of about 2.5 g/cm 3. And the Earth density as a whole is about 5.513 g/cm 3. Because of its buoyancy, the lighter lithosphere rock floats on …
WebThe asthenosphere behaves like a fluid over very long time scales. There are a number of competing theories that attempt to explain what drives the movement of tectonic plates. … WebMar 1, 2024 · The very slow motion of lithospheric plates “floating” on the asthenosphere is the cause of plate tectonics, a process associated with continental drift, earthquakes, the formation of mountains, and volcanoes. In fact, the lava that erupts from volcanic fissures is actually the asthenosphere itself, melted into magma.
WebEarth Sciences questions and answers. The Elastic Rebound Theory predicts that earthquakes can only be generated in the lithosphere – the layer of solid, rigid material. However, based on studies in the Tonga Island, earthquakes occur within the weak ductile asthenosphere. How do scientists explain the occurrence of earthquakes in this weak …
