For many years now, some experts have suggested that the world is broken into more than just seven continents. Though there isn’t a universally accepted definition of a continent, Africa, Antarctica, Asia, Oceania, Europe, North America and South America have traditionally been considered as such. But since 2017 there have been strong claims that an eighth has been overlooked by scientists for many years.
Continents are generally considered to be immense landmasses divided from one another by oceans. However, even this definition is problematic, as the majority of accepted continents aren’t totally detached from their neighbors at all, let alone by large expanses of water. Indeed, continents might better be described as predominately disconnected from each other, rather than wholly so.
In fact, Oceania and Antarctica are the only two of the traditionally accepted continents not connected to other landmasses. For instance, North America and South America are often considered to be two distinct continents. Yet the two are joined by a thin section of territory known as the Isthmus of Panama.
