Few geographical questions seem as straightforward as the number of continents — but ask a dozen people across different countries, and you might hear answers ranging from four to eight, depending on how the world’s landmasses are grouped. Here’s a clear look at the competing models and what they mean for your world map.

Do we have 7 or 8 continents?

Three models dominate the classroom today. One clear pattern: where you live shapes how many continents you count.

Model Continents listed Where taught
7‑continent Asia, Africa, North America, South America, Antarctica, Europe, Australia Most English‑speaking countries (US, UK, Canada, Australia) (Wikipedia)
6‑continent (Americas combined) Asia, Africa, America, Antarctica, Europe, Australia Latin America, Spain, Portugal, France, Italy (Mental Floss)
8‑continent (Zealandia added) Africa, Antarctica, Australia, Eurasia, North America, South America, Zealandia Geological literature; not yet adopted by most schools (Wikipedia)

The seven‑continent model: Asia, Africa, North America, South America, Antarctica, Europe, Australia

  • This is the standard in Australia, Canada, the UK, and the US (Wikipedia).
  • ScienceFocus lists the seven as Oceania (rather than Australia), Europe, Antarctica, South America, North America, Africa, and Asia.

The six‑continent model (Americas combined)

  • Greece and many Romance‑speaking countries treat North and South America as a single continent called “America” (Wikipedia).
  • Some European countries also combine Europe and Asia into Eurasia, yielding six continents (Wikipedia).

The eight‑continent model including Zealandia

  • In 2017, scientists proposed Zealandia as a submerged continent of ~4.9 million km² (Wikipedia).
  • A 2021 study found part of Zealandia is Precambrian and twice as old as previously thought (Wikipedia).
Why this matters

The seven‑continent model isn’t wrong — it’s just one of several valid ways to divide the planet. The eight‑continent model adds a geological layer that schools haven’t caught up to yet.

The catch: The seven‑continent model remains the most practical for everyday use, but geology supports an eighth.

For most people, the seven‑continent model works fine; geologists now advocate for eight including Zealandia.

What is the 9th continent in the world?

No widely accepted ninth continent exists today. But history and geology offer some candidates.

Historical proposals for a 9th continent

  • Some 19th‑century models included a separate “Indian Subcontinent” continent, but that idea faded (Mental Floss).
  • The hypothetical landmass “Lemuria” was posited to explain lemur distribution; it is no longer accepted (Wikipedia).

Zealandia as candidate for 8th, not 9th

  • Zealandia is sometimes mistakenly called the 9th continent; it is actually the proposed 8th (Wikipedia).
  • Currently, Earth has seven recognized geological continents (including Zealandia) according to some geologists (Wikipedia).
The catch

While Zealandia is geologically a continent, educational systems still treat it as part of Oceania. Even if you accept Zealandia, there is no ninth — the debate stops at eight.

The pattern: No consensus exists beyond eight continents.

Historical proposals like Lemuria have been discarded; Zealandia is the only viable candidate for an eighth.

What is the largest continent in the world?

Asia takes the crown on both land area and population, dwarfing all other continents.

  • Asia covers 44.6 million km², about 30% of Earth’s land area (Worldometer).
  • It also has the largest population — over 4.6 billion people in 2025 (Worldometer).
  • The second‑largest continent, Africa, is 30.3 million km² — about two‑thirds of Asia’s size (Worldometer).
The upshot

Asia is the largest continent by every metric — but its eastern and western boundaries are culturally defined, not geologically fixed, which is why Russia is counted as part of both Europe and Asia.

What this means: Asia’s dominance is clear, but its boundaries are cultural.

Asia leads in area and population, but its boundaries are not geologically rigid.

What continent is Russia in?

Russia is a transcontinental country: roughly 77% of its landmass lies in Asia, and 23% in Europe.

  • The Ural Mountains form the traditional continental boundary, placing most of Russia’s territory in Asia (Mental Floss).
  • Culturally and politically, Russia is often considered part of Europe due to its historical and economic ties (Wikipedia).
  • This dual identity is one reason the continent count isn’t fixed — a single country can belong to more than one continent.
What to watch

In the seven‑continent model, Russia is in two rows; educators resolve it differently depending on whether they prioritize geography or politics.

The implication: Russia’s dual identity shows how continent counts depend on perspective.

Russia straddles Europe and Asia, illustrating that continental boundaries are not absolute.

What continents no longer exist?

Geological time has erased entire continents. Some are submerged, some broken apart, some mythical.

Lost continents: Zealandia, Lemuria, and Pangaea

  • Zealandia is mostly submerged (94% underwater) but still a geological continent; it’s not “gone” — just hidden (Wikipedia).
  • Lemuria was a hypothetical landmass proposed in the 19th century to explain biogeographic patterns; it is no longer accepted (Wikipedia).
  • Pangaea was a supercontinent that broke apart about 200 million years ago; its pieces became today’s continents (YouTube).
  • Australia’s crust is the oldest on Earth, dating back over 4 billion years (Mental Floss).

The implication: Continents are not permanent. They drift, split, and submerge. The seven we teach today are just a snapshot.

“There are basically only two major continents: America and Afro‑Eurasia, if you separate Antarctica, and then everything else is just connected.”

— Geologist Valentin Rime, quoted in Mental Floss

“Most English‑speaking countries recognize seven continents.”

— Wikipedia article on Continent

“ScienceFocus says there are four‑continent, five‑continent, six‑continent, and seven‑continent responses depending on how a continent is defined.”

— ScienceFocus

For travelers and educators, the most useful answer remains seven; for geologists, eight is gaining support.

Geological time shows continents are temporary; the current seven are a snapshot of a dynamic planet.

The debate over how many continents exist often surprises people, and how many continents there are explores why some models count five, six, or seven.

Frequently asked questions

Why do some countries teach 6 continents instead of 7?

Many Latin American and European countries combine North and South America into a single continent called “America,” reducing the total to six (Mental Floss). Some also merge Europe and Asia into Eurasia.

What is Zealandia?

Zealandia is a mostly submerged continental crust (94% underwater) that includes New Zealand and New Caledonia. It was proposed as a geological continent in 2017 (Wikipedia).

Is Antarctica considered a continent?

Yes, Antarctica is a continent — the fifth‑largest by area. It is covered by ice and has no permanent population, only seasonal research stations (Worldometer).

Which continent has the most countries?

Africa has 54 recognized sovereign states, the most of any continent (Worldometer).

How are continental boundaries decided?

Continental boundaries are based on a mix of geology (tectonic plates), geography (oceans), and tradition. No single authority sets them; different regions use different conventions (Wikipedia).

What was the first continent on Earth?

The oldest known continental crust is in Australia, dating to about 4.4 billion years ago (Mental Floss). The first continents formed after Earth’s crust cooled.

Can a country be on two continents?

Yes — Russia, Turkey, Egypt, Kazakhstan, and others are transcontinental countries, meaning they span more than one continent (Wikipedia).
