How many continents are there?

The seven-continent model is standard in English-speaking countries and much of Asia. In parts of Europe and Latin America, students often learn six continents, treating the Americas as one. Another model combines Europe and Asia into Eurasia, since they share one landmass. The Olympic rings represent five inhabited continents, leaving out Antarctica. Geologists also discuss Zealandia, a mostly submerged continent beneath New Zealand. Asia is the largest continent by area and population, and Australia (often grouped as Oceania) is the smallest.
