Scientists and geologists have discovered something shocking on the Earth’s map. The continent of Africa is splitting in two, which means that a new ocean could form over time. This split could change almost everything within the region. The climate, ecosystem, and the way humans live will be transformed totally. However, the shifting of tectonic plates is not a new event or phenomenon.
For the past 20 years, scientists have been aware that Africa is gradually dividing. The East African Rift, a 35-mile-long crack in the desert, first appeared as a result of earthquakes that struck Ethiopia in 2005. It marked the start of a long process in which the African plate was splitting into two tectonic plates: the Somali plate and the Nubian plate, Unilad stated. Then in 2018, Kenya experienced another fissure along the rift.
Why is the African continent dividing and splitting? The Rift’s Scientific Basis
What is causing this divide is what we call a continental rift. This is when three tectonic plates are moving away from each other. These tectonic plates are the Nubian, Somali, and Arabian plates. This is the same process that transpired in the Atlantic Ocean a million years ago. According to geologists, magma from the Earth’s mantle rises as the plates separate, causing fissures and weakening the land above.
As time goes by, these cracks caused by magma widen, weaken, sink and eventually are filled with water that will then form a new ocean and then the eastern part of Africa will be separated from the main continent itself. This process might sound calculated and rapid; however, it takes millions of years for it to fully separate and form a new continent. At the moment, the average annual divergence of the plates is 0.2 inches (7 millimetres).
Comparing Africa’s Rift with other geological phenomena would reveal that, despite its somewhat revolutionary appearance, this occurrence is very typical and common. The way that South America and Africa seem to blend on a map is easy to see. They were previously landmasses, which explains this. Over time, the Mid-Atlantic Ridge divided the area.
The end result and meaning of this split for Africa
It is quite obvious that the landscape will change, for instance, the climate and ecosystems. There are also both negative and positive consequences of this divide. A new ocean basin will be created because of the expansion of the Rift Valley. Additionally, East Africans may face possibilities as well as challenges as a result of this change, which may have an impact on agricultural methods, biodiversity, and water supplies.
Another meaning for Africa’s split that we need to know is the high risk of earthquakes, land instability and volcanoes. Tectonic activity is pretty hard on the Earth’s crust; hence, the reaction leads to such natural disasters. Having explored the challenges associated with this divide, scientists have expressed that all this will take millions of years to occur; therefore, there is no need for immediate action.
A look at the future of Earth
What can happen is that geologists and researchers can take note of this change and constantly update us on what is happening next and the implications associated with these changes over the next decades or more. The geological history of Earth makes a new continent seem insignificant. Pangea, the enormous landmass that gave rise to all of the continents, broke apart into the continents that exist today.
We will not be alive to witness the continent’s split. But scientists will continue to monitor and learn more about the changes that could transpire because one thing we know for sure is that nature is unpredictable. Who knows, perhaps the Earth will spilt to a certain extent and stop, but that is not a fact, just a thought. Maps of the world may appear entirely different, with a new ocean in place of East Africa.
