First terrestrial discovery of an extremely rare mineral called ringwoodite confirms theory about huge water ‘reservoirs’ 410 to 660 km beneath the surface of our planet, says a team of researchers led by Prof Graham Pearson from the University of Alberta, Canada.
“This sample really provides extremely strong confirmation that there are local wet spots deep in the Earth in this area. That particular zone in the Earth, the transition zone, might have as much water as all the world’s oceans put together,” Prof Pearson said.
"evolutionary origins have the burden of explaining where Earth’s ocean water came from since the planet was supposedly cooling from the collision of space rocks over millions of years.4 Many evolutionists believe that the oceans formed when those molten materials degassed—released water from within their minerals—over a span of 500 million years.
But after all that time, wouldn’t the molten planet steam itself dry? Now, naturalistic stories also face explaining a second ocean—the mantle’s deep water. Will secular researchers have trouble modeling the ways that blistering-hot, ancient Earth rocks could have provided two oceans’ volumes of water?"

We have a major theological conflict between TEism and YECism in this debate...YECism follows the Biblical claim that the earth was once all water...whereas TEism is forced to follow the secular view that it formed from the collision of space rocks.
The Bible makes no mention of a molten planet in Genesis 1. I feel that this is a massive problem for TEism…its the complete opposite of the creation account surely?
I recognize that we are told, in the book of Revelation for example, that the earth will eventually be destroyed by fire, however, that is how God cleanses what sin has corrupted (e.g. Sodom and Gomorrah). The important point is, sin was not in the world prior to Genesis 3.
It comes as no surprise to me that the hydroplate theory surfaced, the discovery of the Ringwoodite specimen adds legitimacy to that theory.
Scientists have been deeply divided about the composition of the transition zone and whether it is full of water or desert-dry. Knowing water exists beneath the crust has implications for the study of volcanism and plate tectonics, affecting how rock melts, cools and shifts below the crust.
“One of the reasons the Earth is such a dynamic planet is because of the presence of some water in its interior. Water changes everything about the way a planet works,” Prof Pearson concluded. https://www.sci.news/geology/science-ringwoodite-oceans-beneath-earth-01806.html
The presence of liquid water on the surface is what makes our “blue planet” habitable, and scientists have long been trying to figure out just how much water may be cycling between Earth’s surface and interior reservoirs through plate tectonics.New Evidence for Oceans of Water Deep in the Earth | BNL Newsroom
What is really interesting is this article and the referenced study
Researchers have looked at how magma forms in the transition zone. First, they analyzed seismic data related to earthquakes and volcanic activity. Then, they synthesized ringwoodite in their lab. They exposed the mineral to the same high temperatures and pressures found in the transition zone. The ringwoodite began to melt, releasing some of its water. The water decreased the melting point of the rock, and this allowed magma to form.(New Evidence of Earth’s Deep Water Cycle Reveals A Virtual Buried Ocean | KQED).
