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 provided diagram depicts information about the islands of Hawaii, which are located in the middle of the Pacific Ocean.

Overall

, there are eight major islands in the Hawaiian chain, and the oldest one dates back to 80 million years,

while

the most recent are developing from numerous eruptions. The tectonic plates change their location slightly every year, causing a movement in the Pacific Ocean.

According to

the data, the eruption process starts deep under the Pacific plate, beginning 2883 kilometres down. The magma moves upwards, resulting in an eruption, which builds up to later develop a new volcano, which will create the base of another island. Turning to the remaining data, the tectonic plates, which are placed on a solid dense rock, are slowly shifting, causing a movement of 7 to 9 centimetres yearly. Because of these processes, various islands have been created, including a relatively large one like Hawaii and small ones like Kahoolaw and Niihau.
