1. Discovering The Largest Island: Greenland
Greenland is the largest island in the world, covering a vast expanse of approximately 2,166,086 square kilometers (836,330 square miles). It is located between the Arctic and Atlantic Oceans and is geographically part of North America, although it is a constituent country within the Kingdom of Denmark.

Greenland is considered an island because it is a landmass completely surrounded by water. While it is geographically close to North America, it is not part of the continent due to its geological structure and separation by bodies of water.
1.2. Who governs Greenland?
Greenland is governed as a constituent country within the Kingdom of Denmark. It has its own parliament and government, which manage most internal affairs, while Denmark handles foreign policy and defense.
1.3. What is the landscape of Greenland like?
The landscape of Greenland is dominated by a massive ice sheet that covers about 80% of its surface. Coastal areas are characterized by fjords, mountains, and tundra. The ice sheet is a significant feature that influences the climate and environment of the region.
