Most people grew up with a simple world map in school where Africa is one solid block of land. Now scientists say that picture is slowly going out of date. According to work highlighted by National Geographic<\/em><\/a> and several research teams, the African continent is tearing along a giant scar that will one day create a new ocean<\/a> between two separate landmasses.<\/p>\n\n\n\n

This breakup is happening along the East African Rift, where the Somali plate is pulling away from the larger Nubian plate. The movement is incredibly slow, only a few millimeters each year, yet over tens of millions of years it will reshape coastlines, trade routes, and even the way future students learn their geography.<\/p>\n\n\n\n

What It Means for Africa to Split in Two<\/h2>\n\n\n\n

Earth\u2019s outer shell is made of huge rocky slabs called tectonic plates<\/a> that float on a softer layer deeper inside the planet. The East African Rift marks the line where the African plate is breaking into two pieces known as the Nubian and Somali plates, which carry most of the continent and the Horn of Africa.<\/p>\n\n\n\n

From the Gulf of Aden down toward Mozambique, the rift stretches for more than 3,000 kilometers like a long, sagging valley. National Geographic<\/em> describes this region as a place where Africa is literally \u201csplitting in two,\u201d<\/a> and where the smaller Somali plate will eventually pull far enough away to stand as its own landmass on a future map.<\/p>\n\n\n\n

A Rift That Started Millions of Years Ago<\/h2>\n\n\n\n

The story did not begin with a single dramatic crack in the ground. Geological evidence suggests the breakup started around 25 to 30 million years ago in what is now northern Ethiopia, when the crust began to stretch and thin. Over time, that slow tug created deep valleys, chains of lakes, and clusters of volcanoes along the rift.<\/p>\n\n\n\n

In a 2018 article for Royal Holloway, University of London<\/a>, geologist Luc\u00eda P\u00e9rez D\u00edaz explained that activity along the eastern branch of the rift became very clear when a huge crack suddenly opened in southwestern Kenya and damaged a major highway. <\/p>\n\n\n\n

She notes that \u201cevery now and again something dramatic happens and leads to renewed questions about the African continent splitting in two,\u201d even though most of the change is too slow for people to notice.<\/p>\n\n\n\n

Measurements from GPS stations<\/a> show that the Nubian and Somali plates are moving apart by only a few millimeters each year, roughly the speed at which fingernails grow. At that pace, experts say, the continent will take tens of millions of years to fully split, although local quakes and small surface cracks can still feel sudden to people living nearby.<\/p>\n\n\n\n

How a New Ocean Could Appear<\/h2>\n\n\n\n

When a continent stretches, the rigid outer rock begins to tear, and hot material from deeper inside Earth rises into the gap. As that magma cools and hardens, it creates new crust, similar to what happens on the floor of existing oceans, slowly building what will one day be seafloor between two pieces of land<\/a>.<\/p>\n\n\n\n

The Afar region, where Ethiopia meets Eritrea and Djibouti, is a special case because the crust there is already very thin and parts of the landscape lie below sea level. Two arms of the rift are already under water in the Red Sea and Gulf of Aden, and scientists expect that once the valley connecting them sinks low enough, seawater will rush in and start filling a brand new ocean basin<\/a> between the separating plates.<\/p>\n\n\n\n
