Scientists are claiming some shocking information about our oceans. An ancient supercontinent disintegration is going hand in hand with the oceans that are flowing through the Earth’s mantle. What is happening is a process named deep water cycle. Water is slipping under Earth’s tectonic plates, and they come out later as underwater volcanoes and vents. The problem is that this in-depth water process is swallowing even more water than the one that it’s going under.
What Are the Scientists Estimations?
Scientists say that if the theory is correct, then three or four of the water from the oceans is locked under the Earth’s mantle. The findings are presented in the journal Geochemistry, Geophysics, and Geosystems by a team of geologists from Norway. The historical evidence of the sea levels is going alongside with the supercontinental cycles that happen at every 300 to 500 million years. Also, the sea levels fluctuation is by more than 200 m. But what is the cause of this drastic shift? Scientists believe that the change is happening because of the volume of the oceans, and this is causing the movement of the continents.
However, all the things that are happening right now are linked to the downfall of the Pangea supercontinent. The Pangea continent (Pangaea) was one of the large landmass 335 million years ago, and it broke into more individual continents around 175 million years ago. Looking more closely, the Pangea continent was a large piece through two eras, the Paleozoic and Mesozoic. When this rupture began, the deep water cycles have swallowed more than 130m from the world’s oceans. So the North Atlantic Ocean was born, with the North American Plate and the Eurasian Plate being separated.
Drawing to a close, all this rapid event forced rapid subduction of water into the Earth’s mantle somewhere around 230 million years ago. Even so, the warming of the oceans and the melting of the icebergs are still making the water level to rise. If the deep water cycle is changing the sea levels, at the same time, climate change is doing the same with the sea levels.
