Earth's lithosphere, which constitutes the hard and rigid outer vertical layer of the Earth, includes the crust and the uppermost mantle. The lithosphere is underlain by the asthenosphere which is the weaker, hotter, and deeper part of the upper mantle. The lithosphere–asthenosphere boundary is defined by a difference in response to stress. The lithosphere remains rigid for very long pe… Web9 apr. 2024 · The scientific theory of plate tectonics describes how the Earth's lithosphere, consisting of several tectonic plates made up of both continental and oceanic crust, moves on the semi-fluid asthenosphere.These plates interact through different types of boundaries, and their movement is driven by forces such as mantle convection, gravitational sliding, … WebThe lithosphere–asthenosphere boundary (referred to as the LAB by geophysicists) represents a mechanical difference between layers in Earth's inner structure.
