Seafloor plate tectonics: is it real? •During the late 1960s, scientists became interested in exploring the seafloor. In particular, they wanted to find signs of plate tectonics. This includes: Volcanoes Earthquake faults Mountains Hot springs? Oceanic Physiographic Map (Heezen & Tharp, 1977) How Alvin helped solve a long-standing mystery
