Hundreds of millions of years ago, a supercontinent called Pangea formed. For about 125 million years it contained almost all the dry land on Earth. Since then, parts of Pangea have separated and recombined in new ways.

But what is the largest continent today? What about the youngest?

The answer depends on what counts as a continent. According to the CIA World Factbook , the largest continent is Asia. Asia covers more than 44 million square kilometers. Africa is the next largest continent, followed by North America, South America, Antarctica, Europe and Australia.

But geographers have argued about continents since ancient times. Continents are large areas of land mostly surrounded by water, but this definition leaves room for interpretation. Today, Europe and Asia are sometimes combined and called "Eurasia". Likewise, many children in Latin American countries like Chile learn America as one continent instead of two. Altogether, the Americas have an area of ​​just over 42 million square km, larger than Africa but still smaller than Asia.

In some interpretations, Australia is the smallest continent, at just under 8 million square km. However, geologists define continents differently and add at least one more continent that is even smaller.

Rising seas can cover continental rocks. Continental rock can also be stretched and thinned, pushing it partially below sea level. This is the case of New Zealand. The islands of New Zealand are the highest points on a mostly submerged continent with an area of ​​nearly 5 million square km. According to research published in the Geological Society of America in 2017, that continent is called Zealandia, and "geologists consider it a continent," Stock said.
