Name the three type of islands in Oceania and how they are created

Oceania is a region made up of thousands of islands throughout the Central and South Pacific Ocean. It includes Australia, the smallest continent in terms of total land area. Most of Australia and Oceania is under the Pacific, a vast body of water that is larger than all the Earth’s continental landmasses and islands combined. The name “Oceania” justly establishes the Pacific Ocean as the defining characteristic of the continent.
