Answer
The region of the earth that John Tuzo Wilson believed was broken into plates was the “Hotspots” i.e. The Hawaiian Island.
Explanation
The two major contributions of John Tuzo Wilson towards the solidification of the theory of plate tectonics were the introduction of hotspots and the recognition of transform boundaries. The earlier scientific arguments concerning plate tectonic theory was the existence of volcanically active areas present in the middle of plates. The lack of explanation was addressed by John Tuzo who used the Hawaiian island as an example of an island chain that is volcanically active which was a sticking point for some opponents of the plate tectonic theory. He explained that the origins of volcanic rocks in such places are plumes rising from hotspots within stable core of mantle convection cell.
