The miracle described in the Koran: 16 places where you can see the boundaries between reservoirs

While exploring the water expanses in the Strait of Gibraltar, Jacques Yves Cousteau discovered an amazing fact: the existence of two water strata that do not mix with each other. They seem to be separated by a film and have a clear border between them. Each of them has its own temperature, its own salt composition, animal and plant life. These are the waters of the Mediterranean Sea and the Atlantic Ocean touching each other in the Strait of Gibraltar.

A similar phenomenon was described 1400 years ago in the Qur'an in the 19th verse of Surah Rahman, it is mentioned about the barrier between two seas ready to meet, which, however, do not merge with each other.

It is not such a rare picture — a visible border between communicating water spaces: two seas, a sea and an ocean, a river and a tributary, etc. And yet, it always looks so unusual that you can't help but wonder: why don't their waters mix?

The meeting point of the North Sea and the Baltic Sea near the city of Skagen, Denmark. Water does not mix due to different densities.

The meeting point of the Mediterranean Sea and the Atlantic Ocean in the Strait of Gibraltar. The water does not mix due to the difference in density and salinity.

The meeting point of the Caribbean Sea and the Atlantic Ocean in the Antilles.

The meeting point of the Caribbean Sea and the Atlantic Ocean on the island of Eleuthera, the Bahamas. On the left — the Caribbean Sea (turquoise water), on the right-the Atlantic Ocean (blue water).

The meeting point of the Suriname River and the Atlantic Ocean in South America.

The confluence of the Uruguay River and its tributary in the province of Misiones, Argentina. One of them is cleaned for the needs of agriculture, the other becomes almost red with clay during the rainy season.

Six miles from Manaus in Brazil, the Rio Negro and Solimoins rivers join, but do not mix for 4 kilometers. Rio Negro has dark water, and Solimoins has light water. This phenomenon is explained by the difference in temperature and flow rate. The Rio Negro flows at a speed of 2 km/h and a temperature of 28 degrees Celsius, and Solimoins flows at a speed of 4 to 6 km/h, and a temperature of 22 degrees Celsius.

The confluence of the Moselle and Rhine rivers in Koblenz, Germany. The Rhine is lighter, the Moselle is darker.

The confluence of the three rivers Ilz, Danube and Inn in Passau, Germany. Ilts is a small mountain river (in the 3rd photo in the lower left corner), the Danube in the middle and the Inn is light in color. Although the Inn is wider and fuller than the Danube at the confluence, it is considered a tributary.

The confluence of the Alaknanda and Bhagirathi Rivers in Devaprayag, India. Alaknanda is dark, Bhagirathi is light.

The confluence of the Irtysh and Ulba rivers in Ust-Kamenogorsk, Kazakhstan. The Irtysh is clean, the Ulba is muddy.

The confluence of the Jialing and Yangtze Rivers in Chongqing, China. The Jialing River stretches for 119 km. In the city of Chongqing, it flows into the Yangtze River. The clear waters of the Jialing meet the brown waters of the Yangtze.

The confluence of the Irtysh and Om rivers in Omsk, Russia. Irtysh is cloudy, Om is transparent.

The confluence of the Irtysh and Tobol rivers near Tobolsk, Tyumen region, Russia. Irtysh — light, cloudy, Tobol-dark, transparent.

The confluence of the Chuya and Katun Rivers in the Ongudaysky district of the Altai Republic, Russia. The water of the Chui in this place (after the confluence with the Chaganuzun River) acquires an unusual cloudy white lead color and seems dense and dense. Katun is clean and turquoise. Joining together, they form a single two-color flow with a clear border and flow for some time without mixing.

The confluence of the Green and Colorado Rivers in Canyonlands National Park, Utah, USA. Green is green, and Colorado is brown. The channels of these rivers run through rocks of different composition, which is why the colors of the water are so contrasting.

The confluence of the Rhone and Arve rivers in Geneva, Switzerland. The river on the left is the transparent Rhone, which comes out of Lake Leman. The river on the right is the muddy Arv, which is fed by many glaciers of the Chamonix Valley.
