WebEarth'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. Web12 okt. 2024 · Most transform plate boundaries occur in the oceanic lithosphere where they connect segments of ridges (spreading centers). Since the two lithospheric plates slide past one another along the transforms, these boundaries are active seismic zones, producing numerous shallow eartquakes.
