•how does magnetism support the theory of the continental drift?

Chemistry 03.03 Plate Tectonics: Past, Present, and Future All of this plate movement over time really mixes things up! If we look at how plates move and look back in time, we are able to come up with some predictions of how the Earth used to look. These predictions are called the theory of continental drift.The Continental Drift Theory is now called Plate Tectonic Theory. The Plate Tectonic Theory states that all of the continents of the Earth were once one big landmass. This landmass is named Pangaea. 

It is the second answer
