Final answer:
The Hawaiian Islands formed at a hot spot in the middle of the Pacific plate, where heat rises from the interior of the Earth, generating a chain of volcanic islands.
Step-by-step explanation:
The Hawaiian Islands formed at a hot spot in the middle of the Pacific plate. A hot spot is an area far from plate boundaries where heat rises from the interior of the Earth. The Hawaiian hot spot has been active for at least 100 million years and has generated a 3500-kilometer-long chain of volcanic islands.
