Final answer:
E. J. Tuzo Wilson is the geophysicist who first proposed the concept of transform boundaries being connectors between spreading centers, an important element in the theory of plate tectonics. The correct answer is E. J. Tuzo Wilson.
Step-by-step explanation:
The geophysicist who first proposed that a transform boundary is the connector between two spreading centers was E. J. Tuzo Wilson.
This proposal was an important component of the development of the theory of plate tectonics.
While Alfred Wegener originated the concept of continental drift, suggesting that the continents were once connected in a supercontinent called Pangea, it was J. Tuzo Wilson who later expanded upon this, contributing to the understanding of the tectonic processes occurring at plate margins.
Wegener's observations set the stage for later geophysicists, including J. Tuzo Wilson, to develop the theory of plate tectonics, which describes the large-scale movements of Earth's lithosphere.
This theory emerged in the mid-20th century, implicating mechanisms such as seafloor spreading and transform faults, which Wilson specifically addressed, in the dynamic nature of our planet's surface.
Therefore, the correct answer is E. J. Tuzo Wilson.
