This Indian Ocean archipelago consists of 26 atolls made up of over 1,000 coral islands. The average ground level is only 1.5 meters above sea level, making it the world's flattest country. It is also the smallest country in Asia by both population and area. The country is at extreme risk from rising sea levels – scientists predict it could become uninhabitable by the end of this century. The government has already purchased land in other countries (India and Sri Lanka) to potentially relocate its population.

What is the world's largest island that is not an independent country but a territory of Denmark? This massive island is 2.1 million square kilometers (816,000 square miles) – about three times the size of Texas. It is the world's largest island that is not a continent. About 80% of its surface is covered by an ice sheet that contains 10% of the world's fresh water. If this ice sheet melted completely, global sea levels would rise by 7 meters (23 feet). Despite its size, the population is only about 56,000 people, making it the least densely populated territory on Earth. The indigenous people are called Inuit.

Which large island in the Mediterranean Sea is divided between two countries: the Republic of Cyprus and the Turkish Republic of Northern Cyprus? This island has been divided since 1974 when Turkey invaded the north following a coup backed by Greece.
