Hi there!

The mountain of Hawaii was formed by underwater volcanic eruptions. The Bolen lava from this cooled and formed hard rock, gradually building up the island of Hawaii.

Hope this helps!

This process that the mountain in Hawaii was formed by was actually due to the "volcanic activity and also disruption". So, when the volcanoes erupt and so on, they would form this mountain, and as they do so, they was then the result of when the  mountain in Hawaii was formed.
