Frequently Asked Questions
Q1. Which is the largest island in the world?
Greenland is the largest island in the world, covering approximately 2.13 million square kilometres. Located between the Arctic and Atlantic oceans, it is an autonomous territory within the Kingdom of Denmark. Most of its surface is covered by a massive ice sheet, while settlements are concentrated along the coastline.
Q2. Why is Australia not considered the world’s largest island?
Although Australia is surrounded by water, geographers generally classify it as a continent rather than an island. It has its own continental landmass and tectonic plate. Therefore, Australia is excluded from standard island rankings, allowing Greenland to be recognised as the largest island in the world.
