Web1 apr. 2024 · The lithosphere (from the Greek word lithos meaning “stone”) is a thick and brittle layer that comprises the entire crust and uppermost layer of the upper mantle. It has an average thickness of 100 km but can reach up to 300 km in the thickest portions of continents. 2. Asthenosphere WebThe lithosphere may be relatively dehydrated, which would enhance its strength. In contrast, asthenospheric hydration could make it relatively weak and also reduce its melting temperature. A small amount of partial melt beneath the plate in the asthenosphere may exist, which could further ease convection and therefore define the plate.

"WebThe new theory clarified the requirement that there must be an outer rigid layer to the Earth (the lithosphere) decoupled from an underlying layer of lower strength (the asthenosphere). The hypothesis that the Earth has an asthenosphere can be tested by searching experimentally for a layer with physical properties attributable to its low strength.
