Rocks in Australia preserve evidence that plates in Earth’s crust were moving 3.5 billion years ago, a finding that pushes back the beginnings of plate tectonics by hundreds of millions of years.

About 1000 kilometers off the coast of Portugal, hidden beneath the surface of the Atlantic Ocean, lies one of the most interesting geological features on Earth. Stretching roughly 500 kilometers, the ...

Africa is slowly tearing apart, a process that could lead to a massive land collision creating mountains taller than the Himalayas. This geological shift, driven by mantle convection, will reshape ...

Vast, quasi-circular features on Venus’ surface may reveal that the planet has ongoing tectonics, according to new research based on data gathered more than 30 years ago by NASA’s Magellan mission. On ...
