Final answer:
Convincing evidence for the support of plate tectonics theory came from studies of paleomagnetics, earthquakes, and shapes of continents
Step-by-step explanation:
Convincing evidence for the support of the plate tectonics theory came from studies of paleomagnetics, earthquakes, and shapes of continents. Paleomagnetics involves studying the Earth's magnetic field recorded in rocks. By comparing the magnetic orientations of rocks on either side of a mid-ocean ridge, scientists were able to confirm the existence of seafloor spreading. Earthquakes also provided evidence for plate tectonics, as they occur along plate boundaries, indicating the movement and interaction of tectonic plates. The shapes of continents, such as the jigsaw-like fit of South America and Africa, provided further support for the theory of plate tectonics.
