Scientists have uncovered the earliest evidence of tectonic activity on Earth, dating back 3.5 billion years. Analysis of ancient rocks in Australia reveals that segments of the Earth's crust were already moving relative to each other at this time. This finding contributes significantly to the ongoing debate surrounding the origins of plate tectonics and provides valuable insights into the planet's early geological processes. The research offers a new perspective on how the Earth's surface evolved over billions of years, shaping the continents and oceans we know today.
