The mystery of how the Nile flows for 30 million years can finally be solved



The Nile River is one of the most inspiring natural wonders of the world. And that can be so amazing for a long time. New research shows that it has brought water, irrigation and life for 30 million years.

This latest study also presents a solution to the longstanding mystery of the Nile River: why it has not shifted and changed course over time, as is usually the case with rivers of this size and heritage. [19659003] The new study claims that beneath the Nile – a convection cell – a section resembling a conveyor belt – rotates under the Nile – a convection cell – that holds the river in place and shows that it passes through the same region for tens of millions of years.

"One of the big questions about the Nile is when it came about and why it has existed for such a long time," says geologist Claudio Fakenna of the University of Texas at Austin. "Our decision is actually quite exciting."

The competing hypothesis is that the Nile was first created nearly 6 million years ago, when a drainage of the drainage basins related to the East African divide occurred.

While the 30 million-year hypothesis is not entirely new, this latest study provides new evidence for this, including new geological modeling and juxtaposition of volcanic rock from the highlands of Ethiopia with the rest of the Nile Delta.

Changes in the mantle of the Earth are responsible for the emergence of Ethiopian mountains, the study said. This gentle drop of 1

.5 kilometers (almost one mile) in height by the time the Nile reaches the Mediterranean has kept the river going for so long.

Without this geological setting, the Nile would have long ago shifted its direction to the west. This, of course, would have a profound effect on the history of human civilization as well – so important was the Nile to North Africa and the Middle East.

In addition to providing evidence that the Nile is flowing in its present direction for 30 million years, the new study also provides new information on how the movement of the deep mantle beneath the Earth's surface can affect what is happening on earth and how rivers can affect us they give clues to what's going on underneath.

Researchers now want to apply the same type of analysis to other major rivers in the world, including the Yangtze and Congo rivers. For now, however, we may have noted another of the mysteries surrounding the great Nile.

"Despite the many small scale modifications that the Nile drainage has undergone over the last 30 million years, the river has been continuously connecting the Ethiopian topographic swamp to the Mediterranean," the researchers conclude in a published article.

The studies were published in Nature Geoscience .
