Scientists interested in the construction of the rock layers immediately under the Earth´s crust, the lithosphere and asthenosphere, have new tools to help analyze these layers and further understand plate tectonics. The researchers have been using seismic waves to study the lithosphere-asthenosphere boundary, or LAB. This boundary is where the hot, convecting mantle asthenosphere and the overlying cold and rigid lithosphere meet. It has been found that seismic waves move faster...
