Greenland is significantly smaller than Africa; it’s a common misconception that they are similar in size due to map projections. COMPARE.EDU.VN offers in-depth comparisons to clarify such geographical distortions, helping you understand the true scale of our world. Explore spatial awareness and cartographical projections to gain a clearer understanding.
1. Understanding the Size Discrepancy: How Big Is Greenland Really?
The size difference between Greenland and Africa is vast. Greenland, the world’s largest island, covers approximately 2,166,086 square kilometers (836,330 square miles). Africa, on the other hand, is a massive continent spanning around 30,370,000 square kilometers (11,730,000 square miles). This makes Africa about 14 times larger than Greenland.
1.1 Why Does Greenland Appear Larger on Maps?
Greenland’s perceived size on many world maps is distorted due to a cartographic projection called the Mercator projection. This projection, created in 1569 by Gerardus Mercator, was designed for nautical navigation. While it accurately represents the shapes of landmasses, it severely distorts their sizes, especially those located far from the equator.
1.2 The Mercator Projection Explained
The Mercator projection is a cylindrical map projection where a spherical globe is projected onto a cylinder. The cylinder is then unwrapped into a flat map. To preserve the shape of countries, the projection stretches areas near the poles, making them appear much larger than they are in reality. This is why Greenland and Antarctica look disproportionately large on standard world maps.
