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 interiors of rocky planets and moons tend to be pretty hot compared with their surfaces. This heat, which can be caused by a number of sources — such as tidal stretching and compression, the ...

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 ...

A new analysis of Venus’ surface shows evidence of tectonic motion in the form of crustal blocks that have jostled against each other like broken chunks of pack ice. The movement of these blocks could ...

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 ...

Map of Earth's principal tectonic plates. Earth's lithosphere. Major and minor plates. arrows indicate direction of movement at plate boundaries. Vector illustration. Billions of years ago, Earth's ...

Ancient plate tectonics in the Archean period differs from modern plate tectonics in the Phanerozoic period because of the higher mantle temperatures inside the early Earth, the thicker basaltic crust ...

Scientists used satellite data to confirm that Earth's crust is "dripping" into the mantle beneath Turkey's Central Anatolian ...

A new analysis of 30-year-old data suggests something strange is happening within Earth’s evil twin—and it could mean the planet is alive. Venus might be hell, but don’t call it a dead planet. Amid ...

A study led by Prof. Yong-Fei Zheng at University of Science and Technology of China focused on the development of tectonic processes along convergent plate margins through inspection of recent ...
