Which of the following is NOT one of the seven continents?

The correct answer is based on the understanding of the seven continents recognized in geography: Asia, Africa, North America, South America, Antarctica, Europe, and Australia. Atlantis, mentioned in the option, is a legendary island that is often considered a myth rather than a geographical location. It is a story attributed to ancient Greek philosophy, particularly by Plato, and is commonly referred to in literature and popular culture.

In contrast, North America, Asia, and Europe are all widely recognized and defined landmasses on Earth, each with distinct geographical, cultural, and political characteristics. Understanding the distinction between real continental landmasses and mythological or fictional entities is crucial in geography and social studies.
