Final answer:
The hypothesis of plate tectonics was verified by radioisotope data and the reversal of magnetic polarity recorded in the ocean floor.
Step-by-step explanation:
The hypothesis of plate tectonics was eventually verified by radioisotope data recorded in the ocean floor and the reversal of magnetic polarity recorded in the ocean floor. These pieces of evidence supported the idea that the Earth's plates were moving and that new crust was being formed at mid-ocean ridges. The radioisotope data provided information about the age of the oceanic crust, while the reversal of magnetic polarity showed a pattern of alternating magnetic fields on the ocean floor, indicating the spreading of the ocean floor. Shifting coral reefs along the beaches, on the other hand, are not directly related to the verification of plate tectonics.
