Explanation:

Hawaii is an archipelago formed in the middle of the Pacific Ocean, made up of 132 islands, of which only 8 are inhabited. This is explained by the fact that the state (one of 50 belonging to the United States of America) is located in one of the most volcanic areas in the world. This is what geology regards as a "hot spot" - thermal anomaly points within the earth. That is, points responsible for the volcanism that happens inside the tectonic plates. That is why all the islands of Hawaii are made up of volcanoes and have their territory increasing in length every day due to their constant eruptions.
