Our transcription: Plate tectonics has become one of the major unifying theories of Earth Sciences.

In many ways it's comparable to the Theory of Evolution in life sciences.

It provides that unifying theme upon which we can understand and by which we can understand a very wide array of processes, which are taking place in the Earth's crust.

So, I think it's quite clear that it is probably the most important contribution, which has been made to geological thought in much of its development.
