What Are the 7 Continents? Names, Sizes, and Facts
You’ve probably recited the names of the seven continents since grade school, but the list isn’t as simple as it seems. While Asia, Africa, North America, South America, Antarctica, Europe, and Australia/Oceania make up the standard lineup, the number and boundaries of landmasses are far from settled.
Number of continents recognized: 7 (conventional model) · Largest continent by area: Asia (44.6 million km²) · Smallest continent by area: Australia/Oceania (8.5 million km²) · Continent with most countries: Africa (54) · Continent with fewest countries: Antarctica (0)
Quick snapshot
- There are seven continents in the most widely taught model (Worldometer (geography reference site)).
- Asia is the largest continent by both area and population (Worldometer (geography reference site)).
- Australia is moving north at about 2.7 inches per year due to plate tectonics (Encyclopaedia Britannica (science reference)).
- Whether Zealandia should be recognised as an eighth continent remains debated among geologists (Encyclopaedia Britannica (science reference)).
- The use of “Oceania” vs “Australia” for the smallest continent varies by region (Encyclopaedia Britannica (science reference)).
- Australia is drifting north at roughly 2.7 inches per year, gradually shifting the continent’s position (Encyclopaedia Britannica (science reference)).
- Ongoing mapping of Zealandia could lead to wider acceptance of an eighth continent (Encyclopaedia Britannica (science reference)).
The table below highlights key facts about the conventional seven-continent model.

List of the 7 continents with key facts
- Asia: Largest continent, area ~44.6 million km² (Worldometer (geography reference site)).
- Africa: Second largest, area ~30.4 million km² (Worldometer (geography reference site)).
- North America: Third largest, area ~24.7 million km² (Worldometer (geography reference site)).
- South America: Fourth largest, area ~17.8 million km² (Worldometer (geography reference site)).
- Antarctica: Fifth largest, area ~14.2 million km² (Worldometer (geography reference site)).
- Europe: Sixth largest, area ~10.2 million km² (Worldometer (geography reference site)).
- Australia/Oceania: Smallest, area ~8.5 million km² (Worldometer (geography reference site)).
| Continent | Area (million km²) | Number of countries | Population (approx.) |
|---|---|---|---|
| Asia | 44.6 | 48 | 4.7 billion |
| Africa | 30.4 | 54 | 1.4 billion |
| North America | 24.7 | 23 | 600 million |
| South America | 17.8 | 12 | 430 million |
| Antarctica | 14.2 | 0 | 0 |
| Europe | 10.2 | 44 | 750 million |
| Australia/Oceania | 8.5 | 14 | 44 million |
What is the order of the 7 continents by size?
From largest to smallest by land area: Asia → Africa → North America → South America → Antarctica → Europe → Australia/Oceania (Worldometer (geography reference site)).
Which countries belong to each continent?
Asia comprises about 48 countries, Africa 54, North America 23, South America 12, Antarctica 0, Europe 44, and Australia/Oceania 14 (Worldometer (geography reference site)).
The seven-continent model is the most common in English-speaking schools, but its boundaries are cultural as much as geological. The line between Europe and Asia, for example, follows a human convention—not a distinct plate boundary (Encyclopaedia Britannica (science reference)).
Are there 7 or 8 continents?
What is the 8th continent called?
The eighth continent is called Zealandia—a mostly submerged landmass that includes New Zealand, New Caledonia, and surrounding seafloor (Encyclopaedia Britannica (science reference)).
Evidence for and against Zealandia as a continent
- For: Zealandia meets geological criteria: elevated crust relative to ocean floor, distinct geology, and large size (~4.9 million km²).
- Against: 94% of Zealandia is underwater; conventional education systems stick with seven continents.
What is the 8th continent called?
Zealandia is the proposed eighth continent. Researchers have mapped its crust and argue it fits all scientific definitions of a continent (Encyclopaedia Britannica (science reference)).
Because 94% of Zealandia sits underwater, acceptance as a continent depends on whether you prioritise surface area or crustal geology. The outcome affects maps used by millions of students.
Is Oceania a continent?
Difference between Australia and Oceania as continent names
Oceania is often used as the continent name instead of Australia to include the Pacific islands of Melanesia, Micronesia, and Polynesia. The Encyclopaedia Britannica (science reference) notes that some geographers prefer Oceania.
Which countries are part of Oceania?
- Australia, New Zealand, Papua New Guinea, Fiji, Solomon Islands, Vanuatu, and many smaller island nations (UN Statistics Division M49 (geographic classification body)).
What continents no longer exist?
Examples of ancient supercontinents
Pangea, Rodinia, and Gondwana all broke apart over hundreds of millions of years (Encyclopaedia Britannica (science reference)).
Which country is drifting away?
Australia is moving north at about 2.7 inches per year due to plate tectonics (Encyclopaedia Britannica (science reference)).
We treat continents as fixed landmarks, yet the land beneath our feet moves constantly. Australia’s northward drift of 2.7 inches per year is tiny on a human scale, but over millennia it will shift entire ecosystem zones.
Clarity check
Confirmed facts
- Seven continents are widely taught in schools (Worldometer (geography reference site)).
- Asia is the largest and most populous continent (Worldometer (geography reference site)).
- Australia is moving north at about 2.7 inches per year (Encyclopaedia Britannica (science reference)).
What’s unclear
- Whether Zealandia should be an eighth continent is debated among geologists (Encyclopaedia Britannica (science reference)).
- Whether Oceania is a valid continent name is contested in some regions (Encyclopaedia Britannica (science reference)).
- Whether the seven-continent model will be widely replaced by an eight-continent model in education is uncertain (Encyclopaedia Britannica (science reference)).
“A continent is one of Earth’s large continuous masses of land. The number of continents depends on the criteria used.”
Encyclopaedia Britannica (science reference)
“The seven-continent model is the most widely taught, especially in English-speaking countries.”
Worldometer (geography reference site)
For students and educators, the seven-continent model offers a clear framework. For geologists, the push for an eighth continent—Zealandia—highlights the tension between teaching convention and scientific evidence. The choice between Oceania or Australia as the continent’s name exposes regional divides. For mapmakers and textbook authors, the implication is clear: stick with the standard list, but add a note about Zealandia, or risk being outdated within a decade.
