Plate tectonics are 3.6 billion years old, oldest minerals on Earth reveal - zircon crystals Live Science - May 17, 2021
Earth's tectonic plates have moved continuously since they emerged a whopping 3.6 billion years ago, according to a new study on some of the world's oldest crystals. Previously, researchers thought that these plates formed anywhere from 3.5 billion to 3 billion years ago, and yet-to-be published research even estimated that the plates are 3.7 billion years old. The scientists on the new study discovered the onset date of plate tectonics by analyzing ancient zircon crystals from the Jack Hills in Western Australia. Some of the zircons date to 4.3 billion years ago, meaning they existed when Earth was a mere 200 million years old - a baby, geologically speaking. Researchers used these zircons, as well as younger ones dating to 3 billion years ago, to decipher the planet's ongoing chemical record.

The tectonic plates that cover Earth like a jigsaw puzzle move about as fast as our fingernails grow, but over the course of a billion years that's enough to travel across the entire planet .

"Most people follow increasing earthquake activity in the Pacific as well as the recently split Indian Ocean Plate but I live on the Atlantic seaboard and this is what rings true for me. The bottom line is all of the tectonic plates are broken so it's just a matter of time until the first 'domino' falls as the others follow suit. The Atlantic Ocean is widening. "
Here's why. Live Science - January 28, 2021
The Atlantic Ocean is getting wider, shoving the Americas to one side and Europe and Africa to the other. But it's not known exactly how.
A new study suggests that deep beneath the Earth's crust, in a layer called the mantle, sizzling-hot rocks are rising up and pushing on tectonic plates - those rocky jigsaw pieces that form Earth's crust - that meet beneath the Atlantic. Previously, scientists thought that the continents were mostly being pulled apart as the plates beneath the ocean moved in opposite directions and crashed into other plates, folding under the force of gravity. But the new study suggests that's not the whole picture. The research began in 2016, when a group of researchers set sail on a research vessel to the widest part of the Atlantic Ocean between South America and Africa; in other words, to the middle of nowhere.
