Why do South America and Africa have similar coastlines?
Continental Drift Evidence suggested that Pangaea began to break up about 200 million years ago. By 160 million years ago, continents had begun to drift to their present locations. Today's coastlines of South America and Africa are a match because these two continents were once joined together.
Why do continents fit together?
