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
Canadian Society for the Study of Rhetoric Canadian Society for the Study of Rhetoric The Canadian Society for the Study of Rhetoric (CSSR) is a bilingual scholarly society based in Canada that is open to scholars involved in the teaching or researching of rhetoric.
