2. The Hawaiian Islands were formed by volcanic activity over a hotspot in the Earth’s crust, with the Big Island (Hawaii) being the youngest at approximately 400,000 years old, while Kauai is the oldest main island at about 5.1 million years old.
3. Mauna Kea on the Big Island is technically the world’s tallest mountain when measured from its base on the ocean floor, standing 33,500 feet tall, compared to Mount Everest’s 29,032 feet above sea level.
