How Big Is Greenland Compared To Australia? This is a question COMPARE.EDU.VN can help answer by providing a detailed size comparison between Greenland and Australia, exploring their geographical, geological, biological, and anthropological differences. Understanding the comparison of landmasses offers valuable insight, so let us compare sizes, explore why one is a continent and the other an island, and see the contrast of their physical dimensions.
1. Understanding the Basic Geography
Australia, often referred to as an “island continent,” spans approximately 3 million square miles (7.7 million square kilometers). This makes it the smallest continent on Earth. Greenland, on the other hand, covers about 836,000 square miles (2.16 million square kilometers). That makes it the world’s largest island.
1.1 Australia: The Island Continent
Australia’s unique status as both an island and a continent stems from its geographical isolation and substantial size. It’s surrounded by oceans, much like an island, but its landmass is significantly larger than any other island on the planet.
1.2 Greenland: The World’s Largest Island
Greenland, while vast, doesn’t meet the criteria to be considered a continent. It is part of the Kingdom of Denmark and is geographically located near North America. Its size, though substantial, is considerably smaller than Australia.
2. Size Comparison: Greenland vs. Australia
To put the size difference into perspective, Australia is almost four times larger than Greenland. This difference is a primary reason why Australia is classified as a continent and Greenland is not. The sheer scale of Australia supports its continental designation.
2.1 Visualizing the Difference
Imagine overlaying Greenland onto Australia. You could fit nearly four Greenlands within the boundaries of Australia. This comparison highlights the vast difference in land area between the two.
2.2 Why Size Matters
Size plays a crucial role in determining whether a landmass is considered a continent or an island. Continents are typically much larger and more complex geologically and biologically than islands.
3. Geological Differences
Geology is a key factor in distinguishing continents from islands. Continents usually have complex geological structures and are located on separate tectonic plates.
3.1 Tectonic Plates
Australia sits on its own tectonic plate, known as the Australian Plate. This plate is separate from other major continental plates. Greenland, however, is part of the North American Plate.
3.2 Continental Crust
The continental crust beneath Australia is distinct and has evolved over billions of years. Greenland’s crust is more closely associated with that of North America, reinforcing its status as an island.
4. Biological Distinctions
The biodiversity and unique species found in a region also help determine its classification. Continents often have a greater variety of endemic species compared to islands.
4.1 Endemic Species in Australia
Australia is renowned for its unique flora and fauna, including kangaroos, koalas, and eucalyptus trees, which are found nowhere else in the world. This high level of endemism supports its continental status.
4.2 Greenland’s Biodiversity
Greenland has less biodiversity, and fewer endemic species compared to Australia. Its plant and animal life is more closely related to that of North America and the Arctic region.
5. Anthropological Factors
The human history and cultural distinctions of a region can also contribute to its classification. Continents often have distinct indigenous populations with unique cultural histories.
5.1 Aboriginal Australians
Australia is home to the Aboriginal people, who have inhabited the continent for over 60,000 years. Their unique cultural heritage and history are integral to Australia’s identity as a continent.
5.2 Inuit People of Greenland
Greenland’s indigenous population, the Inuit, are part of a larger group of peoples found throughout the Arctic regions of North America and Russia. While their culture is distinct, it is not exclusive to Greenland, unlike the Aboriginal culture in Australia.
6. Defining a Continent: The Criteria
There is no strict scientific definition of a continent. However, several criteria are commonly used to distinguish continents from islands. These include geological, biological, and anthropological factors, as well as size.
6.1 Geological Criteria
Continents are typically located on separate tectonic plates and have complex geological histories. Australia meets this criterion, while Greenland does not.
6.2 Biological Criteria
Continents often have a high degree of biodiversity and many endemic species. Australia’s unique flora and fauna support its continental status, while Greenland’s biodiversity is less distinctive.
6.3 Anthropological Criteria
Continents may have distinct indigenous populations with unique cultural histories. The Aboriginal people of Australia provide a strong anthropological distinction, whereas Greenland’s Inuit population is part of a broader Arctic cultural group.
7. Why Greenland Isn’t a Continent
Despite its large size, Greenland does not meet all the criteria necessary to be classified as a continent. Its geological connection to North America, lower biodiversity, and shared indigenous culture with other Arctic regions prevent it from being considered a continent.
7.1 Tectonic Plate Connection
Greenland shares a tectonic plate with North America, which is a significant factor in its classification as an island rather than a continent.
7.2 Biological Overlap
Greenland’s plant and animal life is similar to that of North America and the Arctic, lacking the unique endemic species that characterize continents like Australia.
7.3 Cultural Affiliations
The Inuit people of Greenland share cultural ties with other Arctic populations, which does not provide the distinct anthropological identity often associated with continents.
8. A Deeper Dive into Australia’s Continental Characteristics
Australia’s unique characteristics extend beyond mere size, encompassing a rich geological history, distinct biodiversity, and a unique anthropological heritage. These elements collectively solidify its status as a continent.
8.1. Geological Stability and Diversity

8.3. The Cultural Heritage of Aboriginal Australians
The Aboriginal Australians, with their deep connection to the land and rich cultural traditions, represent a unique anthropological dimension. Their history and heritage are integral to Australia’s continental identity.
9. Exploring Greenland’s Unique Island Identity
While Greenland does not qualify as a continent, its unique identity as the world’s largest island is equally fascinating. Its icy landscapes, distinctive ecosystems, and the culture of the Inuit people contribute to its unique charm.
9.1. The Arctic Ecosystem and Glacial Landscapes
Greenland’s landscape is dominated by glaciers and ice sheets, shaping its unique Arctic ecosystem. This environment supports a variety of specialized species adapted to the harsh conditions.
9.2. Flora and Fauna of the Arctic
