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 ...

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 ...

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 ...

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 ...

Plate tectonics is the theory that Earth's outer layer is made up of plates, which have moved throughout Earth's history. The theory explains the how and why behind mountains, volcanoes, and ...

The theory of plate tectonics is a interesting story of continents drifting from place to place breaking apart, colliding, and grinding against each other. The plate tectonic theory is supported by a ...

Our world’s surface is a jumble of jostling tectonic plates, with new ones emerging as others are pulled under. The ongoing cycle keeps our continents in motion and drives life on Earth. But what ...

Scientists say they have evidence of a new continental rift forming in southern Africa that could eventually develop into a ...

When the plate sinks into the mantle it melts to form magma. The pressure of the magma builds up beneath the Earth's surface. The magma escapes through weaknesses in the rock and rises up through a ...
