That theory was initially ridiculed, but it paved the way for another theory called plate tectonics that scientists have now accepted to explain how Earth’s continents move.

WebApr 23, 2024 · By Andrew May According to the theory of plate tectonics, the continents are not rigidly fixed to the surface of the Earth. These huge land masses, referred to as plates, gradually change position relative to each other as they slide over underlying material. WebAt the time, the planet was much warmer than today, but the fragmentation of Pangaea led to massive changes in land distribution and ocean and atmospheric circulation patterns, triggering radical climate change. Collisions between plates have triggered further change.
