WebNov 22, 2024 · Recent studies of global seafloor basalts demonstrate that lithosphere thickness variation exerts the primary control on the compositions of these basalts, especially those erupted on intraplate ocean islands with varying lithosphere thickness at the time of eruption (Humphreys and Niu, 2009; Niu et al., 2011; Niu, 2016; Niu and … 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… diversity action plan sample
