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
Drift whale whale is no longer a benefit to a community, but an expensive disadvantage. Many cetacean species have been documented as drift whales, but some are more common than others. In New England, for example, the carcasses of fin, humpback, sperm, right, and pilot whales, as well as dolphins, are most likely to drift ashore. Some species have a naturally high buoyancy, and float when they are dead, aided by the gases of putrefaction. Whales that live in the pelagic ocean, far from the continental shelf, are less likely to wash up ashore than coastal species. Once these deep-sea animals do
