- He observed seafloor cracks similar to existing cracks in the continents.
The answer is D. he observed seafloor cracks similar to existing cracks in the continents.
Explanation:
The plate tectonic theory is considered as an improved version of the continental drift theory. The geophysicist, John Tuzo Wilson has made contribution that support the plate tectonic theory.According to this theory, the plate is the uppermost earth's crust. The theory is based on convection, which states the excess heat in the core of earth causes the molten rock in the mantle layer, to rise up, cool and then sink down. One of Wilson's findings was that he observed cracks in the seafloor that were similar to existing cracks in the continents. He suggested the presence of hot spot for the source of volcanic rocks.
