Is a New Ocean Forming in Africa?
Is a New Ocean Forming in Africa?
The African continent is slowly splitting apart, creating a new ocean basin in the process. This is a rare and fascinating geological phenomenon that scientists have been studying for decades. In this post, we will explain how a new ocean is forming in Africa, how long it will take, and what it means for the world.
How a New Ocean is Forming in Africa
The formation of a new ocean in Africa is related to the structure and movement of the Earth’s crust. The Earth’s crust is made up of several large, solid rock pieces called tectonic plates. These plates float on top of a layer of molten rock called the mantle, and they move slowly over time. The movement of the plates causes various geological events, such as earthquakes, mountains, faults, and volcanoes.
A new ocean is forming in Africa because three tectonic plates are pulling away from each other. These plates are the Arabian, Nubian, and Somali plates. They meet at a junction called the Afar Triple Junction, which has a Y-shaped appearance.
The Afar Triple Junction is the only place on Earth where one can study how a continental rift becomes an oceanic rift. A rift is a crack or a gap in the Earth’s crust, where molten rock from the mantle can rise to the surface. The rift in Africa is called the East African Rift, and it extends through Ethiopia, Kenya, Tanzania, and other countries.
The East African Rift started to form about 30 million years ago, when the Arabian plate began to move away from Africa, creating the Red Sea and the Gulf of Aden. The Somali plate also started to move away from the Nubian plate, creating the East African Rift. The rift is widening and deepening over time, and it will eventually become a new ocean basin.
How Long it Will Take for a New Ocean to Form in Africa
The formation of a new ocean in Africa is a very long process. Scientists estimate that it will take at least 5 to 10 million years for the rift to become wide and deep enough to allow seawater to flow in and create a new ocean. This depends on how fast the plates are moving apart, which varies from 0.5 to 1 cm per year (0.2 to 0.4 inches per year).
The source of water for the new ocean will be the Gulf of Aden and the Red Sea, which are connected to the Indian Ocean. These seas will expand and flow into the East African Rift as the plates separate. This will complete the formation of the new ocean.
The formation of the new ocean will also change the shape of the African continent. The eastern part of the continent will break away from the rest and become a separate and smaller continent. This continent could be called the Somali Continent or the East African Continent. It will include Somalia, Ethiopia, Kenya, Tanzania, Mozambique, Madagascar, and some other countries.
What a New Ocean in Africa Means for the World
The formation of a new ocean in Africa is a significant event for both the geological and the social aspects of the world. This event is a rare phenomenon in the Earth’s geological history. It helps us understand how the Earth was formed, how it changed, and how it continues to change. It also changes the geological map of the world, creating a new ocean and a new continent.
This event is also important for the people living in the African continent. It affects their living conditions, cultures, economies, and politics. It determines the challenges and opportunities they may face in terms of climate change, natural disasters, migration, border disputes, resource sharing, international relations, and more. It also tests their ability to live together and cooperate.
