Web23 mrt. 2012 · The lithosphere-asthenosphere boundary (LAB) beneath ocean basins separates the upper thermal boundary layer of rigid, conductively cooling plates from the underlying ductile, convecting mantle. The origin of a seismic discontinuity associated with this interface, known as the Gutenberg discontinuity (G), remains enigmatic. Web22 jan. 2024 · Isostasy describes the state of balance between the lithosphere and asthenosphere. Isostasy describes the state of gravitational equilibrium in the lithosphere; we can picture this state in Archimedean style as the Earth’s crust floating on a more-dense mantle. Thus, the crust will adjust to loads by moving up or down. impala hatchback

The lithosphere is the solid, outer part of the Earth. The lithosphere includes the brittle upper portion of the mantle and the crust, the outermost layers of Earths structure. It is bounded by the atmosphere above and the asthenosphere (another part of the upper mantle) below. Although the rocks of the … Meer weergeven There are two types of lithosphere: oceanic lithosphere and continental lithosphere.
