Just because Gondwana eventually created the continents we know today, does not mean that these continents will stay the same forever. Eventually, there will be different arrangements in an extensive history of continental adjustment. Continents and landmasses on Earth are always moving in a state of slow motion. Also, at times, many continents come together as one. These supercontinents include Columbia, which is also known as Nuna, Rodinia, Pannotia,…
