How do we know plate tectonics exist (list 4-5 pieces of evidence) and why are there different boundaries?

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.
