Continental drift

is the that the 's continents have shifted relative to one another during geologic time, giving the impression that they have “drifted” over the floor. Abraham Ortelius proposed the that continents ‘drifted' in 1596. Alfred Wegener separately and more extensively established the notion in 1912, but his hypothesis was dismissed by many due to the lack of any motivating mechanism. Mantle convection was later hypothesized by Arthur Holmes as a mechanism for this. The of has subsequently been absorbed into the discipline of , which analyzes the movement of continents as they ride on plates of the 's lithosphere.
