Rodinia

Rodinia was a supercontinent that existed around 1.1 billion to 750 million years ago. It formed when smaller landmasses came together due to tectonic activity and later broke apart. The name "Rodinia" comes from a Russian word meaning "motherland." Its formation and breakup significantly influenced Earth's geology, climate, and the evolution of life, setting the stage for future continental arrangements, including Pangaea. The study of Rodinia helps scientists understand plate tectonics and the history of Earth's surface over geological time.
