How many continents are on Earth?

The correct answer is based on the widely accepted geographical model that identifies seven continents on Earth. These continents are Asia, Africa, North America, South America, Antarctica, Europe, and Australia. Each of these landmasses is distinct in size, population, culture, and biodiversity, contributing to the planet's physical and human geography.

Some regions may use different systems for categorizing landmasses, but the seven-continent model is most commonly taught and understood globally. In contrast, some may consider models that group certain continents together or redefine them, which leads to the ideas of having different total counts. However, according to the conventional understanding and classification, the number of continents on Earth is seven.
