The diagram below gives the information about the Hawaiian island chain in the centre of the Pacific Ocean. Write a report for a university lecturer describing the information shown. Write at least 150 words.

The visualized graph illustrates how the structures of the major islands, situated in the Pacific Ocean, known as the Hawaiian archipelago, which are surrounded by the Ring of Fire mountains, changed over an 80 million-year period. The eruption activities showed the development of the one main island a thousand years ago, which expanded into the seven big islands in recent times.

Initially

, there was the oldest volcano, dating back million years, on the solid, dense rock of the area called the Plate of the Pacific.

Then

, the constant activities of the earth explosion, which originated 2883 km down, produced magma spume.

Moreover

, it developed the youngest crater, which moved 7-9 cm per year in the direction of the shift of the tectonic area. Nowadays, there are seven great atolls in the sea, whose names are Niihau, Kawai, Oahu, Molokai, Kaheolawe, Maui, and Hawaii. The

last

is the biggest holm of all , which is known as the paradise one.

Although
