Continent jig-saw shapes when puzzled and combined together, formed one
big continent - Pangea, and was separated by drifts.
Fossil comparisons of different species were discovered into two
different, separated continents in which when you combine them, they were one
in the past.
Seismic, volcanic, and geothermal activity are found along imagined plate
boundaries.
Plates were actually rubbing against each other as evidence is seen on the
formed mountain ranges.
Paleomagnetism, magnetic field placement in the layers of the rock are
present.
