The number of continents depends on how you define them! There are a few different models used, and which one is "right" can depend on who you ask and where you are in the world. Here are the three most common options:
Seven continents: This is the most common model, especially in the West. It includes:
- Asia
- Africa
- North America
- South America
- Antarctica
- Europe
- Australia
Six continents: This model merges North and South America into a single continent called "America." It's more common in some parts of South America and Europe.
Four continents: This model combines even more landmasses. It merges North and South America into "America," Europe and Asia into "Eurasia," and Africa, Asia, and Europe into "Afro-Eurasia." This model is less common, but it's used in some parts of the world, like Russia and China.
So, the answer to your question is technically "it depends"!
But the most common answer, especially in the West, is seven continents.
Ultimately, it's up to you how you choose to define and count the continents. There's no one "right" answer, and each model has its own merits and drawbacks.
I hope this helps! Let me know if you have any other questions.
