Correct Answer - C
Plate Tectonics. John Tujo Wilson (1965) proposed that the outer surface of earth consists of a jigsaw of thick large and small sized plates of `70-100` km thickness which move relative to one another probably due to convective currents in the semi-molten mantle beneath. This movement is believed to have started about 2000 million years ago with a rate of 6 cm/yr. Consequently the continents are slowly circling the globe. They have already done so four times in the past.
