Are all of the Hawaiian islands the same age?

Is Hawaii slowly sinking?
Slowly, slowly, the Big Island of Hawaii is sinking toward its doom.

Where did Hawaii break off from?
Volcanoes can also form in the middle of a plate, where magma rises upward until it erupts on the seafloor, at what is called a “hot spot.” The Hawaiian Islands were formed by such a hot spot occurring in the middle of the Pacific Plate. While the hot spot itself is fixed, the plate is moving.
