Earth Was Already Moving 3.5 Billion Years Ago, Study Finds

Earth was already moving 3.5 billion years ago, study finds

The story of our planet is written in the slow movement of its surface. Over billions of years, shifting tectonic plates have shaped continents, opened oceans, and created the environments where life could grow and evolve. But one big question has puzzled scientists for decades: when did Earth first begin to move in this way?

Evidence of Fragmented and Mobile Lithosphere on Earth 3.5 Billion Years Ago

Geoscientists have made a groundbreaking discovery by analyzing magnetic signals in 3.5 billion-year-old rocks in Western Australia. This research reveals the oldest direct evidence of global shifts in the Earth’s outer shell, pushing the origins of plate motion back into the planet’s early history. Hadean Earth.

Earth’s tectonic plates were already shifting 3.5 billion years ago

The rocks didn’t look like much from the outside. Scattered across a remote stretch of western Australia called North Pole Dome, they were ancient, weathered, and largely ignored for the better part of Earth’s history. But locked inside those formations, in tiny magnetic minerals no larger than grains of dust, was a record of something that geologists have argued about for decades. Earth’s outer shell was moving. And it was doing so 3.5 billion …

Earth’s Lithosphere was Already Segmented and Mobile 3.5 Billion Years Ago

By tracing magnetic signals preserved in 3.5-billion-year-old rocks in Western Australia, geoscientists have found the oldest direct evidence yet that parts of the planet’s outer shell were shifting across the globe, pushing the origins of plate motion deep into Earth’s early history.
