Lithosphere-Asthenosphere boundary found to become deeper under older crust, thus supporting the suggestion that the discontinuity is closely interrelated to the LAB. Beneath oceanic crust, the LAB ranges anywhere from 50 to 140 km in depth except at mid-ocean ridges where the LAB is no deeper than the depth of the new crust being created. Seismic evidence shows that oceanic plates do thicken with age. This would suggest that the Lithosphere-Asthenosphere boundary underneath oceanic lithosphere also deepens with plate age. Data from ocean seismometers indicate a sharp age-dependent LAB beneath the Pacific and Philippine plates and has been interpreted as evidence for
What on Earth! habits and funeral rites of this "species." The film shows the earth from the view of the Martian flying machines which did not land but used cameras to film earth society. It then follows one average (what it believes to be) earthling and its civilization, by in effect showing a "day in the life" and how they live it. First, it shows one going through dinner with a precisely regulated feeding (vehicle refueling from a gas pump), then it must take its rest (pulling into an attached garage next to a house), because it will have a busy day the
