The Hawaiian island chain is located in the center of the Pacific Ocean, and it contained by one main island Hawaii and several small island. It is formed of volcanoes and the active ones are at the south-east tip of the archipelago, in Hawaii itself.
The oldest island in chain indicate that the whole island group began to form around 80 million years ago. Each island started to evolve after an eruption on the sea floor. The island birth because a ‘hot spot’ existed on the ocean bed, which let out a plume of material called magma. The magma may originate from 2883km deep below the ocean bed. Then, further eruptions took place, and the volcano is built up. Finally, the volcano raise above the surface of the ocean, and it is an embryonic form of island.
The spume of magma has remained static as the Pacific tectonic plate moves in a north-west direction across it at a speed of 7-9cm per year. With the several eruption by ‘hot spot’, an island chain has form.
