What evidence (3 types) did scientists use to prove continental drift? explain?

The evidence of the theory of continental drift can be found on the edges of the tectonic plates. For example, the boundary of the African Plate and the Eurasian plate is in the Mediterranean Sea, just south of the island of Crete. At this boundary, scientists have observed that the Eurasian Plate is sliding under the African Plate at a rate of three to four centimeters per year as the African Plate drifts north
