What is a Continent?

Saharan Africa and Europe – the two continents of our world – have been around for thousands of years. As the world continues to evolve, and as our knowledge of the planet grows, it’s important to understand how we define and categorize continents.

The Definition of a Continent

The definition of a continent can vary, but in general, it is an area of land (or in a few cases, a group of islands) that is considered distinct from other land masses because it is geographically separate, politically self-contained and has its own unique geological character. As such, a continent typically contains many different countries and cultures.

The Seven Continents

The seven most widely accepted continents today are Europe, Asia, Africa, North America, South America, Australia, and Antarctica. These seven continents are believed to have formed around 200 million years ago. Europe and Africa are joined together as one continent, while mainland Australia is attached to the continent of Antarctica.

The other five continents – Asia, North America, South America and Antarctica – are each connected to their own continent. North American and South American borders have shifted in different times throughout history, making their definitions very complex. It is important to note that while the most accepted definition of a continent is seven, some people do include the islands of Hawaii and Madagascar as part of the continent of Oceania.

Challenges to Labeling Continents

Labelling a continent is not always so straightforward. While Europe and Africa are generally understood to be one continent, some people separate the two for different reasons. And when it comes to Antarctica, some people define it as a continent in its own right, while others recognize it as a collection of archipelagos.

One way this debate is being resolved is through the construction of an Electronic Atlas of the World project by the United Nation’s Food and Agriculture Organization. This project will use emerging mapping technologies to create more accurate and detailed maps that will be accessible to anyone with an internet connection. It is hoped that this project will help to establish global agreement on what is considered a continent.

Conclusion

From the tectonic shifts that created the continents millions of years ago to the advances in technology that are helping to define them today, our understanding of the world continues to evolve. While there is no single definitive answer as to how many continents there are, understanding the definition of a continent can help us navigate and explore the many different countries and cultures of our world.
