Why Is Africa Splitting In Two?

You can stamp all you like but the ground beneath your feet still ain’t solid, not really. We all live our lives atop a complex network of puzzle pieces that, thanks to Earth’s hot gooey center, are constantly shifting, generating earthquakes, building mountains, and tearing continents apart – which, by the way, is currently happening to Africa.

It’s pertinent to point out that this seismic split isn’t one you need to worry about, however, and possibly isn’t something we as a species will survive long enough to see. The great breakup is scheduled to take tens of millions of years before we’re looking at a drastically different world, but the change could be quite something.

The emerging crack is associated with the East African Rift System (EARS), one of the largest rifts in the world, stretching downward for thousands of kilometers through several countries in Africa, including Ethiopia, Kenya, the Democratic Republic of the Congo, Uganda, Rwanda, Burundi, Zambia, Tanzania, Malawi, and Mozambique. When it breaks away, it’ll separate the smaller Somalian plate from the larger Nubian plate as part of a painstakingly slow process that’s already been developing for around 25 million years.

A dramatic crack in the Kenyan Rift Valley in 2018 got The Internet very excited about the concept of tearing continents. It was a very impressive fissurebut one that may have had little to do with Africa’s geologic future; some have suggested it was more likely caused by soil erosion. However, its placement is curious.

The process of the great continent of Africa losing its eastern shoulder will be slow and gradual rather than a sudden, cartoon-like split, and when it eventually happens, it’s expected a vast sea will separate the two plates. A shocking concept to the modern-day A wise manbut it’s a story that the Earth has told time and time again.

The Earth as it stands today is a modern development in relation to the planet’s history. Once upon a time, all of the continents were combined into one known as Pangaea, but the action of tectonic plates pulled it apart, creating drifting continents with edges that – if brought together – would slot together like perfect puzzle pieces.

If the puzzle-like nature of the continents doesn’t convince you, there’s also all the fossil evidence we’ve found that shows ancient species living in places that are now geographically separated. This is true of Mesosauran extinct 290-million-year-old genus of reptile, fossils of which have been found in South America and Africa, according to the American Museum Of Natural History.

It’s a seismic split that’s hard to get your head around, and it’s thought that the continents have come together and split apart at least three times in Earth’s history, with more on the way – albeit very, very slowly.

The departure of East Africa appears to be the next in line, but it will be just another move in this giant geological playbook. Whether we as a species will survive for long enough to witness it? Well, that’s a different story.
