Discuss the major sources of evidence for the theory of plate tectonics
Coastlines of the continents fit together like puzzle pieces, and mountain ranges and rock types match across the boundaries. Some evidence of glacial flow only makes sense when continents are put together based on tectonic evidence. Terrestrial fossil ranges span adjacent continents. More recently, paleomagnetism has been used to reconstruct plate positions and spreading center activity.
