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.
