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
Cool the Earth Cool the Earth Cool the Earth Inc. is a non-profit educational organization based in Northern California. The mission of Cool the Earth is to educate kids and their families about climate change and motivate them to take simple measurable actions at home to reduce their carbon emissions. Currently, the organization offers programming to over 100 elementary schools. Cool the Earth was founded in 2007 by Marin County parents, Carleen and Jeff Cullen, in the North San Francisco Bay Area.
