Paleomagnetism and continental drift by the mid twentieth century enough evidence had been amassed to begin openning the minds of many scientists to the idea that the continents could have moved across the surface of the earth.

Continental drift theory - tectonics tectonics == large scale movement of lithospheric plates introduction during ww ii, scientists discovered that the ocean floor was not a flat surface but had some unique relief features like ridges, trenches, seamounts, shoals etc.
Continental drift: continental drift, large-scale horizontal movements of continents relative to one another and to the ocean basins during one or more episodes of geologic time this concept was an important precursor to the development of the theory of plate tectonics, which incorporates it.
