Final answer:
Pangaea and Rodinia were supercontinents that shaped Earth's geological history through their formation and breakup.
Explanation:
Pangaea is the name given to the supercontinent that existed approximately 335 to 175 million years ago. It was formed by the convergence of all the major continents into one landmass before eventually breaking apart into Laurasia and Gondwana.
Rodinia was an even earlier supercontinent that existed around 1.1 billion years ago, preceding Pangaea. Rodinia was a landmass that brought together about 75% of the present continental landmass and eventually fragmented around 750 to 600 million years ago.
Supercontinents like Pangaea and Rodinia play a significant role in the geological history of the Earth, showcasing the continuous cycle of landmass convergence and dispersal over vast periods of time.
