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! What on Earth! What on Earth! (French: "La Terre est habitée!") is a 1966 National Film Board of Canada animated short co-directed by Les Drew and Kaj Pindal. The film is a mockumentary, introduced in its opening credits as produced by the "National Film Board of Mars" that takes a humorous look at car culture from the point of view of fictional Martians, who mistake automobiles for Earth's true inhabitants and people as their parasites. It attempts to examine the sociology of the automobile as the dominant species on earth, and makes wild guesses about the lifestyle, feeding habits, mating
