At some point between 300 million and 1 billion years ago, a large cosmic object smashed into the planet Venus, leaving a crater more than 170 miles in diameter. A team of Brown University researchers ...

12.11.2015: Our planet Earth is the only planet in the Solar System that possesses Plate Tectonics. The Earth's surface is in a constant state of change; the tectonic plates together with the oceans ...

The theory of plate tectonics is strikingly recent in scientific history, which was widely accepted in the early 1960's. Now, scientists have discovered an alternative style to plate tectonics and ...

Earth’s crust looks solid from the surface, but it is broken into a shifting mosaic of slabs that slowly rearrange oceans and continents. Understanding how those tectonic plates first formed is one of ...

The Earth's outer layer is broken into moving, interacting plates whose motion at the surface generates most earthquakes, creates volcanoes and builds mountains. In this image, the orange layer ...

A study of a giant impact crater on Venus suggests that its lithosphere was too thick to have had Earth-like plate tectonics, at least for much of the past billion years. At some point between 300 ...
