john tuzo wilson
harry hess
alfred wegener
dan mckenzie

Explanation:

Harry Hess proposed the theory of seafloor spreading in the early 1960s. He suggested that new oceanic crust is formed at mid - ocean ridges and then moves away from the ridge, which provided a key piece of evidence for the theory of plate tectonics. Dan McKenzie is known for his work in plate tectonics but not specifically for seafloor spreading. Alfred Wegener proposed the theory of continental drift. John Tuzo Wilson is known for concepts like transform faults and hotspots.

Harry Hess
