How many continents are there on Earth?

The Earth is recognized as having seven continents: Africa, Antarctica, Asia, Australia, Europe, North America, and South America. This model is widely accepted in most parts of the world, including in educational systems, geographical studies, and global discussions. Each of these continents has its own distinct geographical and cultural characteristics, which contribute to the diversity of our planet.

In some contexts, people might refer to five or six continents. For example, in certain educational systems, the Americas are often combined into one continent known as "America," leading to a count of six. Similarly, some models consider Eurasia as a single continent due to the massive land connection between Europe and Asia. However, the general consensus, particularly in a global context, is that there are indeed seven continents. Therefore, the answer indicates a standard understanding of Earth's geography.
