The plate tectonics theory established in the 20th century has been successful in interpreting many geological phenomena, processes, and events that have occurred in the Phanerozoic. However, the ...
Have tectonic plates changed speed over the last 3 billion years? The answer has far-reaching implications, as plate tectonics affected everything from the supply of vital nutrients for early life to ...

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 ...
How long ago did plate tectonics – the slow movement of great land plates in Earth’s outer shell – begin? We don’t know for certain. But estimates range from 4 billion years ago to as recently as 800 ...
Researchers used small zircon crystals to unlock information about magmas and plate tectonic activity in early Earth. The research provides chemical evidence that plate tectonics was most likely ...
Early in Earth’s history, the heat left over from the collision that formed the Moon left its surface an ocean of magma. As it cooled, its crust was frequently shattered by massive impacts that ...

How the tectonic plates were formed
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 ...
New finding contradicts previous assumptions about the role of mobile plate tectonics in the development of life on Earth. Moreover, the data suggests that 'when we're looking for exoplanets that ...
Venus and Earth are similar in size and mass, but took strikingly different evolutionary paths. After all, Earth is – at present – an oasis for life. And Venus, the planet next door, is a boiling ...
Life on this planet has a lot going for it. The Earth is not too hot, nor is it too cold. We have just enough carbon dioxide in our atmosphere to prevent a runaway greenhouse effect. We have plentiful ...
