Destruction happens when one plate moves below the other at convergent boundaries. When this occurs, the sea floor grows wider, pushing the two continents apart. Wegner also noticed that rocks and mountain ranges across continents looked similar and were similar ages, the belt of ancient rocks of 2,000 million years ago from the Brazilian coast matches with those from western Africa he also noticed that there were similar geological sequences in eastern Canada and Scotland. This drifting takes millions of years to complete this process. Convergent boundaries can also occur between two continental plates. One of the reasons that dark matter has arisen as a theory is the fact that when we observe certain galaxies, they have much more kinetic energy then the masses in them would suggest, therefore, a separate force must be at play. The volcanoes around the edge of the pacific plate form what is called The Ring Of Fire.Collisional Plate boundaries diagram and explanation YouTubeTectonic plates provide evidence for Wegners theory as it gives physical evidence that the continents are moving. According to the modern day map, these continents are far apart. What pieces of evidence were used to support plate tectonics? In terms of rock composition, at locations where continents match up, the kinds of rocks on the opposite sides of the continents were of the same kind. Evidence for Continental Drift.
