Hel m Hawaii is the world's most remote island population center in the world. The six largest Hawaiian Islands — the Big Island, Maui, Lanai, Molokai, Oahu and Kauai — form a chain of islands running to the northwest. The islands appear in this pattern because they are situated on a volcanic hotspot. A hotspot is an area in the Earth's mantle where plumes of hot molten rock called magma rise up from the mantle, forming volcanos on the Earth's crust. The crust is the outermost layer of a planet. The mantle is the layer below the crust. This process happened with the Hawaiian Islands. They formed one after the other as a tectonic plate, the Pacific Plate, slid over a plume of magma, creating a volcano. The tectonic plate continued to move over the hotspot, and the active volcano lost its connection to the hotspot and became inactive. A new active volcano formed from the hotspot. Which sentence from the Introduction [paragraphs 1-3] BEST introduces the idea of how the Hawaiian islands were created to the reader?
