Based on early observations, including those in the table below, scientists proposed that the continents were once together but had drifted apart. however, scientists could not identify anything that would make them move. new technology, such as a worldwide network of earthquake detectors, led to new observations. then scientists proposed that earth’s surface was divided into tectonic plates that would move as a result of forces linked to earthquakes and the formation of new ocean floor how are continental drift and plate tectonics related? continental drift was the hypothesis that led to the theory of plate tectonics. continental drift was the theory that became the law of plate tectonics. the theory of continental drift was modified based on the new observations to become the theory of plate tectonics. the theory of continental drift was proven false, and the law of plate tectonics took its place.
