Which of the following discoveries was the FIRST to give support to the theory of continental drift? magnetic anomalies from the seafloor on both sides of the mid-ocean ridge varying degrees of thickness for seafloor sediments along the mid-ocean ridge age dating of sediments on both sides of the mid-ocean ridge satellite imaging that enabled us to measure continental movement
