Web5 aug. 2024 · 9) The asthenosphere is closest to the surface of the earth under the oceans. This is because the rocks making up the lithosphere are thinner here, so there is less rock between the asthenosphere and the surface. 10) The place where the lithosphere meets the asthenosphere is called the LAB. We know it sounds like a science joke, but it really ... WebThe ocean island LAB depths were sometimes consistent with predictions for the ocean lithosphere (e.g., 100–110 km beneath 90–100 Myr old lithosphere near the Big Island of Hawaii (Li et al., 2004) but were also interpreted as plume related thinning of the lithosphere (50–60 km) beneath Kauai (Li et al., 2004), although the explanation for the …
