Lithosphere-Asthenosphere boundary Lithosphere-Asthenosphere boundary The Lithosphere-Asthenosphere boundary (LAB) represents a mechanical difference between layers in Earth’s inner structure. Earth’s inner structure can be described both chemically (crust, mantle, core) and mechanically. The Lithosphere-Asthenosphere boundary (referred to as the LAB by geophysicists) lies between Earth's cooler, rigid lithosphere and the warmer, ductile asthenosphere. The actual depth of the boundary is still a topic of debate and study, although it is known to vary according to the environment. The LAB is determined from the differences in the lithosphere and asthenosphere including, but not limited to, differences in grain size, chemical composition, thermal properties, and
What Time Is Love? Noise Terror staged in the week prior to "America"'s UK release, concluded with the announcement of their departure from the music industry. This was later confirmed by a full-page press announcement that used images from the set of the "America: What Time Is Love?" music video.
