Everybody knows what an island is, a piece of land entirely surrounded by water, smaller than a continent; otherwise, it would be recognized as a continent. One is not so sure about Australia, but the fact that Australia has its own tectonic plate justifies it as a continent.

What is an Island Country?
Island countries, island states or island nations are sovereign countries whose territory consists of one or more islands or parts of islands.

How many Island Countries are there?
There are 46 sovereign states and one disputed territory, Taiwan, which consists only of islands.

Geology of Islands.
Some islands are the above sea level part of a volcano or a seamount whose base is on the sea floor. Mauna Kea volcano on the Big Island of Hawaii is such a mountain; it is actually the highest mountain on Earth at 9,330 m (30,610 ft).
Some low-lying tropical islands were formed from organic materials such as corals. Other islands are unsubmerged parts of the continental shelf, the shallow edge of a continental landmass.

Did you know South America is the only inhabited continent without an island nation?
