Continental drift theory Jigsaw puzzle They were once joined Supercontinent Pangaea ( pan- all, gaea- earth)

pangaea Changes occur in Pangaea during geological time period Geological time Permian Million years ago 225 Mya Changes in landmass Pangaea, Tethys sea, pacific ocean is there Triassic 200 Mya Seafloor gets old and cold Jurassic 135 Mya Breaking of Pangaea, climate warmer which kill dinosaurs Cretaceous 65 Mya Break up complete. Atlantic ocean open up. Present day Atlantic ocean is still expanding, continents are still moving
