Full Answer

Lo?ihi only began forming about 400,000 years ago. Several of the other Hawaiian volcanoes, such as Mauna Kea, Kohala and Haleakala, are about 1 million years old. The Ko?olau Range, Wai?anae Range and Ka?ena Ridge, all on O?ahu, are actually the remains of volcanoes that are 2 million to 5 million years old.

The Hawaiian Islands are a chain of islands, also known as an archipelago, located in the Pacific Ocean. There are eight main islands: Hawai?i (the Big Island), Maui, O?ahu, Kaua?i, Moloka?i, Lana?i, Ni?ihau and Kaho?olawe. The Hawaiian Islands are located above a volcanic hotspot, and all of the islands were formed through volcanic activity. As each underwater volcano erupted, the lava cooled and hardened, forming a land mass above sea level over millions of years.
