Which statement about the hotspot at Hawaii is FALSE? A) A hotspot at Hawaii explains the presence of active volcanoes far from a tectonic plate boundary. B) A hotspot is a localized zone of upwelling mantle rock located deep below the moving tectonic plate. C) The age of volcanic rock in the Hawaiian Islands gets progressively older to the west. D) Magnetic reversals are the primary cause for the hotspot at Hawaii.

Question

Quizplus · Accepted Answer

Magnetic reversals are not the primary cause for the hotspot at Hawaii. The hotspot is caused by a plume of hot mantle material rising from deep within the Earth, which melts as it rises and creates volcanic activity. The age progression of volcanic rock at the Hawaiian Islands and other hotspot locations is due to the movement of the tectonic plate over the stationary hotspot, not magnetic reversals.
