What do you think? Kinda like general geographic question =P but well it's here bit tricky to answer this question.
From meaning of the word 'Island' (which is a piece of land surrounded by water), Australia and Antarctica are needless to say the biggest islands in the world. However, they are more commonly known as 'continent'due to its large size of land which somehow more suitable to be named so.
So which island is accepted as the largest island in the world?
The answer is Greenland. Greenland is the world's largest island, which has 840,000 square miles (2,175,590 km2). This is followed by New guinea and world's third is Borneo island.
Some interesting information about the world's largest island. Greenland is not only the world's largest but it's unique in the fact that 81% of the country is ice and glaciers. The coastal edges consist mainly of Tundra and bush Tundra.
