Final answer:
Early Polynesian sailors used Celestial navigation, wave patterns, bird migrations to navigate the Pacific Ocean and colonize new islands.
Step-by-step explanation:
Early Polynesian sailors were able to navigate vast regions of the Pacific by using celestial navigation, bird migrations, and wave patterns. Celestial navigation involved using the stars and constellations to determine their direction and position on the open ocean. Bird migrations were another valuable resource for navigation, as the Polynesians observed the flight patterns of certain bird species that would indicate the presence of nearby land.
Additionally, wave patterns played a crucial role in their navigation, as the Polynesians learned to read the different types of waves and swells to detect the proximity of land or obstacles. By combining these three means, early Polynesian sailors were able to successfully navigate the vast Pacific Ocean and colonize new islands.
