Before there was evidence from rocks and fossils, many scientists theorized
that the continents were once joined together. Using only maps, these
scientists observed that -
1) the oceans have become smaller throughout Earth's history.
2) weathering and erosion have reshaped the surface of the Earth.
3) the continents were all bordered by mountain ranges.
4) the shapes of the continents allowed them to fit together.
