You look at a globe. You see seven distinct landmasses. It feels simple, right? North America, South America, Europe, Asia, Africa, Australia, and Antarctica. That’s what we all memorized for the third-grade quiz. But honestly, the more you look at 7 continents on a map, the more you realize the whole system is kind of a mess.
Geology doesn't care about our maps. Geographers and tectonic plate experts like Dr. Christopher Scotese have been pointing out for years that the "seven" model is more of a cultural agreement than a scientific fact. If you live in Russia or Eastern Europe, you were likely taught there are six continents because Europe and Asia are just one giant slab of rock called Eurasia. If you’re in Latin America, you might have learned that North and South America are just "America," one single continent connected by a thin strip of land.
Maps lie. Or, at the very least, they oversimplify things to keep our brains from exploding.
The Eurasia Problem and the 7 Continents on a Map
The border between Europe and Asia is basically vibes. There is no ocean between them. No massive tectonic rift. Just the Ural Mountains, which, let’s be real, are more like a suggestion than a physical barrier. Historically, we separated them because the Greeks and Romans wanted to distinguish their "civilized" world from the vastness of the East.
Why the distinction still exists
It’s mostly about politics and culture. Even though they sit on the same plate, the historical development of Paris is a world away from the history of Tokyo. This is why when you see 7 continents on a map, Europe looks like a tiny peninsula sticking off the side of Asia. If we were being strictly geographical, we’d call it the Eurasian continent.

But wait, it gets weirder.
Africa is technically connected to Asia by the Isthmus of Suez. Well, it was, until we dug a canal through it. Does a man-made ditch turn one continent into two? Most geographers say yes for the sake of simplicity, but from a purely crustal perspective, Africa is its own massive tectonic entity. It’s moving north, by the way. Slowly but surely, Africa is smashing into Europe. In a few million years, the Mediterranean Sea will just be a mountain range.
The "Island" Continents: Australia and Antarctica
Australia is the odd one out. Is it a continent or the world's biggest island? To be a continent, you generally need to be on your own tectonic plate and have a unique biological identity. Australia hits those marks. It’s got marsupials you can't find anywhere else and sits smack in the middle of the Indo-Australian Plate.
Then there’s Antarctica. It’s a desert. A cold, miserable, ice-covered desert. People often forget it’s actually a landmass under all that ice. If the ice melted—which, let’s hope it doesn't—Antarctica wouldn't look like a solid block. It would look like a jagged archipelago of islands because the weight of the ice has actually pushed the land below sea level in some spots.

Why We Use the 7-Continent Model Anyway
We use it because it’s convenient. Labels help us organize the world. If you’re planning a trip, saying "I’m going to Africa" gives someone a much better idea of your location than saying "I’m going to the Afro-Eurasian landmass."
Maps are tools. Depending on what you’re doing, you might use a different version of the 7 continents on a map layout. Pilots use different charts than geologists. Sailors care about oceans, not landmasses.
The tectonic reality
If we mapped the world by tectonic plates, the map would look like a broken stained-glass window. You’d have the Pacific Plate, the North American Plate, the Nazca Plate... it would be a nightmare for a primary school student to memorize. So, we stick to the seven. It’s a compromise between what the Earth is actually doing and how humans perceive the land they walk on.
Lost and Found: Zealandia and the 8th Continent
You might have heard the buzz a few years ago about Zealandia. Researchers like Nick Mortimer have spent decades arguing that New Zealand isn't just a bunch of islands. It’s actually the highest peaks of a submerged continent.

About 94% of Zealandia is underwater. But it meets all the criteria:
- High elevation compared to the surrounding ocean floor.
- Diverse rock types (igneous, metamorphic, and sedimentary).
- A thicker crust than the standard ocean floor.
If we officially recognize Zealandia, the whole 7 continents on a map narrative goes out the window. Suddenly, we’re at eight. Or maybe we’re at six if we combine Eurasia. The count is always shifting depending on who you ask and what scientific paper just got published.
The Mercator Distortions You Should Know About
Most of the maps you see on a wall use the Mercator projection. It was designed for sailors in 1569. It’s great for navigation because it keeps directions straight, but it’s terrible for showing the actual size of continents.
Greenland looks huge. Like, almost as big as Africa. In reality, you could fit Greenland into Africa about fourteen times. South America is also way bigger than it appears on a standard map. This distortion impacts how we perceive the importance of different regions. When Europe looks central and massive, it reinforces a certain worldview. When you switch to a Gall-Peters projection or a Dymaxion map, the world looks completely different. It’s jarring.
Actionable Insights for Map Enthusiasts and Travelers
If you’re trying to actually understand the world beyond the 2D paper version, here’s how to look at it more accurately:
- Check out the AuthaGraph Map. It’s arguably the most accurate map ever made in terms of representing the actual proportions of landmasses and oceans without those weird distortions. It won’t look like the map you’re used to, but that’s because the world isn't a perfect rectangle.
- Think in terms of "Regions," not just "Continents." Geopolitically, the Middle East is often treated as its own thing, even though it sits at the intersection of Africa, Asia, and Europe. Central America is geographically part of North America but culturally very different.
- Follow the Tectonic Movement. Use resources like the PALEOMAP Project to see where the continents were 200 million years ago and where they are heading. It’ll give you a lot more respect for the fact that the ground beneath your feet is basically a giant raft.
- Stop trusting the size of the North. Use a site like "The True Size Of" to drag and drop countries over each other. It’s a reality check. Dragging the DR Congo over Europe or Canada over South America will change how you view the 7 continents on a map forever.
The Earth is a dynamic, changing thing. The maps we draw are just snapshots in time. Whether there are seven, six, or eight continents really depends on whether you're talking to a politician, a geologist, or a traveler. Next time you look at a map, remember that the lines are mostly just there to help us make sense of the chaos.
