The answer to this is true. Usually when a volcano forms it starts off from the ocean floor then it will form up towards the surface. Volcanoes are also known for creating new islands like for example The Hawaiian Chain, it was created by volcanoes. in order for the islands to form, the plates in the ocean floor aka where the volcanoes are located has to push up another rock aka an island. Molten rock falls into the ocean and hardens creating a new island.
