Continental drift orogeny at the boundaries of convection cells. By 1967, barely two decades after discovery of the mid-oceanic rifts, and a decade after discovery of the striping, plate tectonics had become axiomatic to modern geophysics. In addition, Marie Tharp, in collaboration with Bruce Heezen, (who initially ridiculed Marie's observations that her maps confirmed continental drift theory), provided essential corroboration, using her skills in cartography and seismographic data, to confirm the theory. Evidence for the movement of continents on tectonic plates is now extensive. Similar plant and animal fossils are found around the shores of different continents, suggesting that they were once
Institute for the Study of the Americas English Studies and Institute of Historical Research. Institute for the Study of the Americas The Institute for the Study of the Americas (ISA) was established in 2004 following a merger of the Institute of Latin American Studies and the Institute of United States Studies. ISA formed part of the University of London’s School of Advanced Study along with nine other research institutes. In 2013, the Institute of Latin American Studies was re-established in order to focus the support provided to scholars of Latin America. Activities pertaining to the study of the United States continue within the School of Advanced Study
