WebAsthenosphere geology Britannica [18] This boundary is neither seismically sharp nor well understood[9] but is approximately coincident with the complex 670km discontinuity. Thus, it has been called the low-velocity zone (LVZ), although the two are not strictly the same;[6][7] the lower boundary of the LVZ lies at a depth of 180 to 220 kilometers (110 … 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 …
