Discovering the mysterious phenomenon 'The sea is split in half' on each ocean

Every ocean in the world has a number of areas where the sea surface has been divided into two different water colors.

Nature is always something very magical. It can be dangerous, violent with unbearable strength, but sometimes beautiful, brilliant and magnificent, like the phenomenon in the picture below.

The split sea surface is recorded in Mississippi.

If you want to see more clearly this beautiful scene, please watch the video below.

This "Split Sea" phenomenon video was recorded in Mississippi (USA). Theoretically, it could happen in every ocean in the world, in the "Estuary" areas - where the river flows and flows into the sea. However, rare places have a special separation like the Mississippi River area.

The water area on the left is river water and the right is sea water. Their intersection created this beautiful scene.
But why are sea water and river water not merging, but forming such a strange boundary?

The water area on the left is river water and the right is sea water.

In the past, many cultures explained, the cause of this phenomenon related to spirituality. As the Quran of Muslims said that river water - sea water cannot mix, so the god created a boundary between river water and sea water to save people. Although the sea is large, it cannot take over the river - the source of human fresh water.

In fact, the Quran also has the right idea: sea ​​water and river water simply cannot mix. But the reason is not so simple.

To understand this, it is important to know that the sea on Earth was not as salty as it is today. But when the rain falls, it dissolves salt and minerals on land, then follows the rivers that flow into the sea.

In other words, the ocean is a place to receive salt from every river, so the salinity of the sea is much bigger. And it is the difference in salinity that makes the bilateral water density different and unmixable. Instead, salt water will flow below the source of fresh water above.

This phenomenon not only occurs at the river mouth, but also at the intersection of the two oceans , only the difference in salinity on both sides.
