What is the theory of continental drift?



  1. 0 Votes

    Continental drift is the idea that the continents are not (and have never been) stationary with respect to each other. Geologists theorize that around 500 million years ago, all of Earth’s landmass was grouped together into one massive continent called Pangaea. Pangaea broke into northern and southern parts some 200 years ago: Gondwana in the south and Laurasia in the north. Gondwana and Laurasia “drifted” towards their respective poles, eventually fracturing and forming the modern topography of the Earth. There may have been several other supercontinents prior to Pangaea.
