The movement of rivers. The water pressure of rivers can cut deep into a river bed. Rocks and things from the river bed are carried downstream, creating a narrow channel.
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.
The region that John Tuzo Wilson believed was broken into plates was the "Hotspots" i.e. the Island of Hawaii.
Tuzo Wilson, fully John Tuzo Wilson, (born Oct. 24, 1908, Ottawa, Ont., Can. - died April 15, 1993, Toronto, Ont.), Canadian geologist and -geophysicist who developed global patterns of faulting and the structure of the continents.
John Tuzo Wilson's two major contributions to strengthening the theory of plate tectonics were the introduction of tropical climate and the recognition of transformation boundaries.
Previous scientific debates on the theory of tectonic plates were the existence of volcanic eruptions located between the plates.
Lack of clarity was addressed by John Tuzo who used the island of Hawaii as an example of a volcanic island series that was a stronghold for some opponents of the plate tectonic theory.
He explained that the origin of volcanic rocks in such areas is that pipes come out of the tropics within the stable sphere of the mantle convection cell.
Thus, The region that John Tuzo Wilson believed was broken into plates was the "Hotspots" i.e. the Island of Hawaii.
