On present-day Earth, plate subduction continuously modifies the chemical composition of the convecting mantle, and various mantle sources linked to these processes have been widely studied. However, ...
The movement of the tectonic plates influences the movement of Earth's continents. The Earth we see today, about 336 million ...

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 ...
Rocks in Australia preserve evidence that plates in Earth’s crust were moving 3.5 billion years ago, a finding that pushes back the beginnings of plate tectonics by hundreds of millions of years.
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 ...
A handful of ancient zircon crystals found in South Africa hold the oldest evidence of subduction, a key element of plate tectonics, according to a new study published today in AGU Advances, AGU’s ...

Observations indicate that plate tectonics began before any currently known structural geological record on Earth Identification of the oldest preserved pieces of Earth’s crust in southern Greenland ...
