To get the answer to the question, you need to understand the geological process that led to the formation of the islands of Hawaii. The correct answer is: "The islands sit on hotspots that form volcanoes which then break the ocean surface."
Explanation:
The Hawaiian Islands were formed through a geological process involving hotspots and volcanic activity. A hotspot is an area in the Earth's mantle where heat is constantly being generated from deep within the Earth.
As the Pacific tectonic plate moves over the hotspot, magma rises from the mantle and reaches the surface. This magma erupts as volcanic activity, forming a volcano. Over time, as the Pacific plate continues to move, the volcanic activity creates a chain of islands.
The oldest island in the Hawaiian chain, Kauai, is located farthest northwest and is believed to have formed around five million years ago. As the Pacific plate moves to the southeast, younger islands, such as Oahu, Maui, and Hawaii (also known as the Big Island), were formed in succession.
So, the islands of Hawaii were not formed by older and bigger islands colliding after volcanic eruptions, as stated in the first and second responses. Nor were they formed by the Pacific plates moving and later joining together, as stated in the third response. The correct answer is that the islands sit on hotspots that form volcanoes which then break the ocean surface.
