The 7 Continents and 5 Oceans, Explained
Can you name all seven continents right now? Most adults can't get past five. By the end of this lesson, you'll know all seven — plus the five oceans that connect them.
What Is a Continent?
A continent is one of Earth's seven huge landmasses — much bigger than any single country. Some continents, like Asia, hold dozens of countries. Others, like Australia, are just one. What makes a continent a continent isn't a strict rule — it's mostly history and tradition, passed down from old maps. That's why Europe and Asia count as separate continents even though they're actually connected by land, sitting on one giant landmass sometimes called "Eurasia." Long ago, geographers simply agreed to draw the line at the Ural Mountains in Russia.
The Seven Continents
Here they are, roughly largest to smallest: Asia (the biggest, home to over half of all people on Earth), Africa (the second biggest, with more countries than any other continent), North America, South America, Antarctica (covered almost entirely in ice, with no permanent population), Europe, and Australia (often called Australia/Oceania, since it includes thousands of Pacific islands too). Try this memory trick: A-A-A-N-S-E-A — Asia, Africa, Antarctica, North America, South America, Europe, Australia. Say it a few times and it sticks.
What Is an Ocean?
If continents are Earth's biggest landmasses, oceans are its biggest bodies of water. Oceans cover about 71% of Earth's surface — if you looked at Earth from space, you'd see far more blue than green or brown. Every ocean is technically connected into one giant world ocean, but geographers divide it into five named oceans based on which continents they border.
The Five Oceans
From largest to smallest: the Pacific (the biggest by far — bigger than all the land on Earth combined), the Atlantic (between the Americas and Europe/Africa), the Indian Ocean (bordering Africa, Asia, and Australia), the Southern Ocean (surrounding Antarctica — the newest official ocean, recognized in 2000), and the Arctic (the smallest and coldest, at the top of the world).
How They Connect
Every continent touches at least one ocean — that's part of how geographers figured out where to draw continent lines in the first place. Look at a world map and you'll notice something: oceans mark the borders between continents almost everywhere, except Europe/Asia (which share a land border) and North/South America (connected by a thin strip of land in Panama). Once you can picture which ocean touches which continent, the whole map starts to click into place.
Vocabulary
Continent
One of Earth's seven biggest landmasses.
Ocean

Recap
- • Earth has 7 continents and 5 oceans, and every continent touches at least one ocean.
- • Asia is the biggest continent and the Pacific is the biggest ocean — both bigger than all the others in their category combined.
- • Continent lines aren't a strict rule — Europe and Asia share one landmass but count as separate continents by convention.
