Early Earth was covered in a global ocean and had no mountains

This is part of an article in new scientist magazine:

Our research indicates there were no mountains and continental collisions during Earth’s first 700 million years or more of existence – it was a much more quiet and dull place,” he says. “There are strong similarities with zircon from the types of rocks that predominated for the following 1.5 billion years, suggesting that it took the Earth a long time to evolve into the planet that we know today.”

The team conducted a forensic study of the grains looking for clues to their formation.

They found that the zircon was created by melting old igneous rocks rather than sediments.

“Sediment melting is characteristic of major continental collisions, such as the Himalayas, so it appears that such events did not occur during these early stages of Earth’s history,” says Burnham.

 

Well, this is no news, was in the first chapter of genesis. So no surprises here.
