Scientists discover that the Earth only has six continents not seven

From a young age, we’re taught that the world consists of seven continents, however, new research suggests that this isn’t the case at all.

Forget what you learned in elementary school — The Earth doesn’t have seven continents after all.

From a young age, we're taught that the world consists of Africa, Antarctica, Asia, Oceania, Europe, North America, and South America. However, new research suggests that this isn't the case.

A recent study published in the journal Gondwana Research proposes that we actually have six continents. This extraordinary claim results from detailed research into the geological processes behind the breakup of Europe and North America and how these landmasses have evolved over time.

Dr. Jordan Phethean, the study’s lead author from the University of Derby, explained that his team’s findings indicate, “the North America and Eurasian tectonic plates have not yet actually broken apart, as is traditionally thought to have happened 52 million years ago.”

Instead, these plates are continuing to stretch and are still in the process of breaking apart, rather than being wholly separate entities. In other words, North America and Europe could be considered a single continent rather than two distinct ones.

The study focuses on the volcanic island of Iceland, previously understood to have formed around 60 million years ago due to the mid-Atlantic ridge. This tectonic boundary, formed by the North American and Eurasian plates, is thought to have sparked the emergence of a hot mantle plume that ultimately created the island, as Earth.com notes.

However, by carefully analyzing tectonic movements across Africa, Phethean and his colleagues have challenged this theory and put forward a radical new idea. They argue that Iceland, along with the Greenland Iceland Faroes Ridge (GIFR), contains geological fragments from both European and North American tectonic plates.

This suggests that these regions are not isolated landforms as previously thought but interconnected pieces of a larger continental structure. The scientists have even coined the term “Rifted Oceanic Magmatic Plateau” (ROMP) to describe this new geological feature, which could fundamentally alter our perception of the formation and separation of Earth’s continents.

Phethean describes the discovery as the Earth Science equivalent of finding the Lost City of Atlantis because his team uncovered “fragments of lost continent submerged beneath the sea and kilometers of thin lava flows.”

Furthermore, the researchers have found striking similarities between Iceland and Africa’s volcanic Afar region. If their study proves accurate, this would mean that the European and North American continents are still in the process of breaking apart and are, therefore, still linked. Phethean acknowledges that his team’s findings will raise some eyebrows but insists they are grounded in meticulous research.

“It is controversial to suggest that the GIFR contains a large amount of continental crust within it and that the European and North American tectonic plates have perhaps not yet officially broken up,” he admitted, while stressing that his work supports these hypotheses.

Nevertheless, the research is still in its conceptual phase, and the team aims to conduct further tests on Iceland’s volcanic rocks to obtain more concrete evidence of an ancient continental crust. They are also employing computer simulations and plate tectonic modeling to better understand how the ROMP is formed.

This research follows Phethean’s earlier discovery of a hidden “proto-microcontinent” nestled between Canada and Greenland. This primitive landmass, about the size of England, sits below the Davis Strait, just off Baffin Island.

Phethean noted that “rifting and microcontinent formation are ongoing phenomena” that help scientists better understand the behavior of continents and plate tectonics. Such knowledge can help experts predict how our planet might look in the distant future and locate where useful resources may be found.

Our understanding of Earth's continents might need an update based on these groundbreaking findings. The research suggests that the interconnected nature of North America and Europe challenges long-held geological beliefs and opens new avenues for studying Earth's dynamic processes.

As scientists continue to investigate, the very map of the world we thought we knew may change.
