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.

    How do volcanoes affect people?

  • Q:

    How does a volcano form?

    A:

    A volcano forms when a vent in the Earth's crust allows magma to well up from below. The magma fills a void underneath the surface, and when it builds up enough pressure, it bursts through to the surface. As the magma cools, it hardens into rock, and multiple eruptions may build up the mountainous form of a volcano.

    What happens to create a caldera?

    A:

    A caldera forms as a volcano's magma chamber empties, resulting in a loss of support for the earth above it. These bowl-shaped depressions can range in size from a few hundred meters to several kilometers wide. They are generally caused by large volcanic eruptions.
