The earth has 3 plates boundary's. Divergent, Convergent, and transform. Plate boundary's are where the lithosphere plates meet. Divergent boundary's move away from each other. Convergent boundary's move towards each other. And lastly transform! Transform moves opposite of each other. There are 3 types of convergent boundary's.Ocean/Ocean, Ocean/Continent, and Continent/Continent. Continental drift was first discovered by Wegner. He thought the earth had a super continent called Pangaea. That means that all the continents were once long ago and in along time that will happen. He had 3 pieces of evidence. First, we have coal in PA and coal only forms in tropical climates. Secondly, if you look at a map the continent's seem as if they could fit together like a puzzle piece. Lastly, we found organisms that have been found on other continent's. Those are Wegner's three pieces of evidence.
