 * Only about two sentences, and there was still a redundant statement! I took it out and then believe it or not doubled the size of this article, and it's still only a few lines long.  It's just a quick and dirty addition, please everyone tear it apart and build it bigger with links, data and diagrams! Professor Chaos (talk) 08:41, 28 November 2007 (UTC)

 * Not wrong, just not ideal, but I've reworded that sentence anyway - it was clumsy as it stood whichever word was used. Mikenorton (talk) 23:00, 17 June 2014 (UTC)

Isn't the description of the upper boundary incorrect?
"The upper boundary is defined as the sharp increase in seismic wave velocities and density at a depth of 660 kilometers (410 mi)."

My understanding is that the depth of 660 kilometers marks the boundary between the upper and lower mantle. Other sources define the mesosphere as all of the mantle below the asthenosphere; that is, the upper boundary of the mesosphere is the lower boundary of the asthenosphere and "the lower boundary of the asthenosphere is not well defined" (https://en.wikipedia.org/wiki/Asthenosphere).

Another way to describe the mesosphere is everything between the asthenosphere and the metallic core. — Preceding unsigned comment added by 70.106.198.41 (talk), 20 December 2015 (UTC)
