Rodinia was a supercontinent that existed during the Neoproterozoic era, approximately 1.3 billion to 750 million years ago. The study of Rodinia is significant for understanding the assembly and breakup of supercontinents, the evolution of Earth’s tectonic plates, and the environmental changes that led to the Snowball Earth events.
