Appalachians exhibit Wilson Cycle • Plate tectonic theory divides earth’s crust into plates • Plates diverge apart or rift & a new ocean basin forms • Plate motion reverses & convergence causes collision, & mountain building • The Wilson Cycle records plate motion opening & closing of ocean basins in the rock record
