Sample Problem
Using Plate Tectonics, explain why the Hawaiian
Islands vary in age and amount of volcanic
activity.
Answer The Hawaiian Island chain formed as a
result of the Pacific plate moving over a hot
spot located in the mantle beneath the pacific
ocean. The oldest volcanic islands are located
the farthest from the hot spot and has little to
no volcanic activity. Whereas the closer you get
to the hot spot, the younger the volcanic islands
are and the greater the amount of volcanic
activity. For example, the island of Hawaii is
presently positioned directly above the hot spot
and experiences volcanic activity on a regular
basis.
