Viewed from space, the Paleozoic Earth would be a foreign world. During this era, seas flooded the continents and receded several times. During the early Paleozoic three small continents— Laurentia, Siberia, and Baltica—split apart from the rest of the supercontinent Gondwana and formed the Lapetus Ocean in between.During the early Paleozoic Era, the continents were grouped close to the equator. As they moved apart, the process of seafloor spreading occurred, leading to the formation of new oceanic crust. This process caused the oceans to become deeper as the new crust was created and pushed the older crust away from the spreading center.Thanks to Keeps for sponsoring this video!
