How many oceans are there on Earth? Now the answer to this question has changed, the discovery of the sixth ocean!

There are five oceans on Earth with the Atlantic, Pacific, Indian, Arctic and Southern Ocean. But now the sixth ocean has also been discovered.

How many oceans are present on Earth? If your answer is five, you could be wrong. Actually, till now we knew that there are Atlantic, Pacific, Indian, Arctic and Southern oceans on Earth. However, now an international team of scientists Earth Evidence has been found for the presence of significant amounts of water between the upper and lower mantle of the Earth. This evidence was found during the analysis of a rare diamond. This diamond was formed by being buried 660 km below the surface of the earth.

In this way, the theory is also confirmed that sea water is present along the slab and then enters the transition zone. The new findings suggest that the Earth’s water cycle includes the Earth’s interior. The study, conducted by a German-Italian-American research team, has been published in the journal Nature. It states that Earth’s internal structure and transition is shaped by the 660 km boundary between the mantle transition zone and the lower mantle.

Where is the Sixth Ocean?

Scientists have provided evidence that water may be present in the Transition Zone (TZ). This is the boundary layer that separates the Earth’s upper mantle and lower mantle. This boundary is located at a depth of 410 to 660 km. There is a pressure of up to 23,000 bar, due to which a mineral named olivine comes in its crystalline structure.

Olivine makes up about 70 percent of the Earth’s upper mantle and is also called peridot. Researchers said that at the upper boundary of the transition zone, at a depth of about 410 km, it turns into a dense wadslite. Then at a depth of 520 km, it then takes the form of even more dense ringwoodite.

What have scientists found?

Scientists analyzed a diamond found in Botswana. This diamond was formed 660 km below the Earth’s surface at the interface between the transition zone and the lower mantle. Analysis of the diamond using Raman spectroscopy and FTIR spectrometry revealed ringwoodite inclusions, indicating the presence of large amounts of water.
