Correct Answer:
C. North America
The correct answer is North America. Geographically, Greenland is an integral part of the North American continent, despite its strong political and cultural ties to Europe.
Greenland's Continental Identity
- Tectonic Plate Location: Greenland sits entirely on the North American tectonic plate, which also carries Canada, the United States, and parts of Siberia. This is the primary scientific basis for its continental classification.
- Proximity to Canada: The island is separated from Canada's Ellesmere Island by only the narrow Nares Strait. Its closest neighbours are all North American, not European.
- Political vs. Geographic Distinction: Greenland is an autonomous territory within the Kingdom of Denmark, which is culturally and politically European. However, political ownership does not change geographical fact — just as French Guiana is geographically South American despite being a part of France.
- Why Not the Others? Europe is often mistakenly assumed due to Danish sovereignty, but the nearest European land (Iceland) is over 300 km away. Asia and Antarctica are entirely separate and geographically distant. Greenland is definitely not part of Antarctica, which lies in the Southern Hemisphere.
In conclusion, geographically and tectonically, Greenland is unequivocally part of North America.
