Quizplus · Accepted Answer

American geologists rejected Wegener's idea of continental drift because he could not provide a valid mechanism that would cause continents to shift positions. While he had some evidence supporting the existence of a supercontinent, it was not enough to convince the scientific community at the time. Additionally, the apparent fit of continental coastlines is still debated today, although it has become more widely accepted that the edges of continental shelves rather than sea level should be used to define them.
