Earth is known as the “blue planet” – in an image shaped by the vast oceans that cover three rooms of the surface. However, the color of the oceans seem to be in permanent change. It has been green, now it is blue, then the purple and even red can come.
A study recently in Nature Geology & Evolution suggests that Oceans may be purple in the future.
The same investigation had already amazed the scientists and was news in Zap for revealed that.
But scientists go further and also suggest in the possibility of future color changes in our oceans.
The investigation group, led by Taro Matsuo(Japan), used advanced simulations and found that, at the beginning of our planet, the green light dominated the spectrum during the archenemainly due to a process called iron precipitation.
Researchers found that increased oxygen production eventually reacted with iron, transforming it from ferrous iron soluble into insoluble iron-soluble.
As explained, how ferric iron is insoluble, precipitates in the form of rust -like particles.
This heavy iron absorbed the blue light, while the red wavelength was absorbed by the water, leaving the Green light dominate the underwater view.
The future “Purple and Red Planet”
The observations were made around the Japanese volcanic island of You have to People and suggest that the color of the oceans seem to be in permanent change. It was already green, now it is blue, then it can be the purple and even red.
More than the theory that the oceans were green and that initially the earth was the “green planet, the researchers’ theoretical models suggest that future oceans can assume totally different shades under varied environmental conditions.
For example, if sulfur levels increase, the oceans may seem purple due to intense volcanic activity and low oxygen level in the atmosphere.
In the same way, Oceans can shine in red under tropical climates Intense, when red iron oxides form from the decomposition of the rocks and the rivers pour them into the oceans.
