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 ...

The emergence of plate tectonics in the late 1960s led to a paradigm shift from fixism to mobilism of global tectonics, providing a unifying context for the previously disparate disciplines of Earth ...

For decades, scientists have accepted a particular theory regarding the evolution Earth’s plate tectonics, but a recent study published in Nature Geoscience could defy this as a team of researchers ...
