The Diagram Below gives information about the Hawaiian Islands chain in the centre of the Pacific Ocean. Write a report for a university lecturer describing the information shown.
The picture depicts information about the Hawaiian Islands chain, situated in the middle of the Pacific Ocean.
Overall, the Hawaiian island is the largest among the Islands of the Pacific Ocean, comprising some ancient volcanoes. However, the movement of tectonic plates to the western side of the Ocean each year causes several volcanic activities.
The Hawaiian island is the largest among the eight islands of the Pacific Ocean, with some tiny islands such as Nihau also being found in the Ocean. The Pacific Ocean experiences tectonic plate movement drifting apart around 7 to 9cm each year. This has resulted in many volcanoes being formed in one of the major islands, the Hawaiian Islands.
As illustrated in the diagram, Hawaiian Island had suffered major volcanic eruptions, with the oldest dating back some 80million years ago. The volcanic eruption process begins to form some 2883km below the solid, dense rock. Eventually, a spume is formed, which remains immobile on the Hot spot. Until tectonic plates drift to the north-western angle of the ocean some 7 to 9 centimetres, magma spume flows through the solid, dense rock, initiating another volcanic activity.
