Briefly explain how the Hawaiian Island chain formed. The definitions of hot spot and mantle plume should be included in your explanation
The Hawaiian Island chain formed as the Pacific plate traveled over a hot spot on the Earth's surface created by a mantle plume. A hot spot is a location on Earth's surface where a stationary column of magma, originating deep within the mantle--a mantle plume, has slowly risen to the surface and formed a volcano. Because the mantle plumes apparently remain stationary within the mantle while the plates move over them, the resulting hot spots leave a trail of extinct and progressively older volcanoes. This trail of extinct volcanoes is the Hawaiian Island chain.
