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 to the north Recent censuses have shown a slowing of the rate of drift, with increasing numbers of North Islanders heading to the South Island's popular scenic regions such as Central Otago. Drift to the north Drift to the north is a term used in New Zealand to refer to the internal migration of people from the South Island to the country's main metropolitan area, Auckland, in the northern North Island. The term is especially common in the cities of Christchurch and Dunedin, university cities whose graduates frequently head either to Auckland or the country's capital Wellington (also in the North Island) after
