In Greek, the word 'Pangaea' means 'all lands' . It is derived from Ancient Greek "Pan" which means "entire" and "Gaia" means "Earth". Pangaea was a super continent that existed around 200 million years ago before it split up. Their breaking up appears to have been cyclical through Earth's history.
