Did you know Greenland can look gigantic on some maps and tiny on others? That's because no flat map can show the round Earth perfectly.
The Earth is a three-dimensional sphere, but maps are two-dimensional.
Mapmakers use projections to create a flat map, similar to flattening out an orange peel, but this process always causes some stretching or distortion.
Let's look at a few commonly used projections.
The Mercator projection projects Earth's curved surface onto a cylinder, accurately showing areas near the equator but distorting shapes and sizes near the poles.
Countries like Greenland appear much more prominent on the Mercator map than in reality because landmasses farther from the equator are stretched.
Another method is the conic projection, in which the Earth's surface is represented as if covered by a cone, making it more suitable for polar regions.
This projection is most accurate where the cone shape touches the globe along a specific line of latitude, usually the equator.
A map projection is a way to show the Earth’s round surface on a flat piece of paper or a screen. Since Earth is a sphere, flattening it always causes some distortion—meaning shapes, sizes, or distances may not be perfectly accurate. Scientists and cartographers (mapmakers) use different projections depending on what they need to show.
Each projection has strengths and weaknesses, and no single map can perfectly represent Earth. Scientists and geographers choose the best projection based on what they need to study or display.
Maps are models of the real world. Different map projections change how the Earth appears, making some areas look bigger or smaller than they actually are.
As you explore, ask these questions:
Maps have evolved over time. Long ago, people made simple sketches of land and water. Today, satellite technology and GPS allow us to create detailed, interactive maps. Even the way we use maps has changed; now, we can pull out a phone and find our location instantly.
Maps also help us track changes on Earth, such as expanding cities or shifting coastlines. By studying different maps, you can see how the world changes over time and how maps play a key role in exploring, learning, and understanding our planet.
