Webb24 mars 2010 · Now, researchers have developed a new model of the Earth - two decades in the making - to predict the movement of one plate relative to another. The model, called MORVEL for "mid-ocean ridge... WebbIn this model, plates move through a combination of pull from the weight of the subducting edge of the plates, and through the outward pushing of an ocean ridge where magma is …

Webb4 maj 2015 · The geologists reasoned that two such sinking plates would provide twice the pulling power, doubling India’s drift velocity. The team found relics of what may have been two subduction zones by sampling and dating rocks from the Himalayan region. WebbPlate movement is imperceptible on a human timeframe (common use of fingernail growth analogy is only true for slowest plates and underestimates importance of motion). Plate motion is rapid enough that continent collision can cause financial and political chaos, while rifting can divide families or separate a species from its food source.
