This task is submitted by our student Vansh Soi. 

The diagrammatic view elucidates the information regarding the Hawaiian island chain located in the centre of the Pacific Ocean. Overall, the chain constitutes notable eight major islands with the oldest volcano ranging back to 80 million years. 

According to the provided diagram, the Pacific tectonic plates under the Pacific Ocean are in constant motion, moving about 7 to 9 centimetres each year over a solid dense rock beneath them. This shift of plates causes the eruption to initiate, nearly originating at 2883 kilometres below the ocean surface. Furthermore, a number of such eruptions lead to the formation of a younger volcano. Afterwards, magma spume could be found just above the plates; however, 'hot spot' spume tends to be static below the plates. In addition, the oldest marked volcano in the Hawaiian island chain dates back an astounding 80m years. 

Besides this, Hawaii demonstrates to be the largest island in the whole chain, spread as far as over 100 km. On the contrary, Niihau, Kahoolawe and Lanai illustrate to be the tiniest of all. Moreover, Oahu, Kauai, and Molokai manifest to be roughly 50km long each. At last, Maui depicts to be larger than the majority of others, with its approximate length of 70kms.
