Could Earth be a 'waterworld'? It may have started that way

Perhaps Kevin Costner's famously bloated 1995 film "Waterworld" deserves more credit.
A new study suggests that our planet could have been entirely covered in water, after all, about 3.2 billion years ago, researchers said.
In order to investigate ancient Earth, the University of Colorado Boulder researcher Boswell Wing and study co-author Benjamin Johnson had to dig up the dirt evidence for ancient oceans.
And they found a chunk of it sitting in Northwestern Australia's outback, at a site called Panorama. https://edition.cnn.com/

Scientists May Have Solved Case of ‘Geologic Amnesia’

As billions of years have passed since its formation, Earth’s rocks tell the tale of its history, except for “geologic amnesia” sites around North America scientists claim to have figured out in a study released Monday.  In sites like the Grand Canyon and the base of Pikes Peak, rocks dating back about 550 million years sit atop more ancient rock layers, some dating back more than 3 billion years, leading geologists to wonder what happened in the years in between. In a study published in the Proceedings of the National Academy of Sciences, geologists led by Rebecca Flowers from the University of Colorado Boulder aimed to discover the reason behind the phenomenon scientists call the Great Unconformity. https://www.courthousenews.com/
