Volcanoes on the ocean floor erupt to create oceanic islands, often referred to as volcanic islands. Oceanic islands are also called as "high islands," regardless of their height. Low islands are continental and coral islands, which can be hundreds of metres taller than high islands. Even though they are encircled by water, continents are not categorised as islands because of their size. The smallest continent, Australia, is more than three times larger than the largest island, Greenland. In every ocean, lake, and river in the world, there are innumerable islands.
