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 ...
A geologist has revealed intriguing insights into the volcanic activity on Mars. He proposes that Mars has significantly more diverse volcanism than previously realized, driven by an early form of ...
A seamount sitting on a subducting tectonic plate off the coast of Japan and plowing its way into Earth's mantle may be at the root of several magnitude 7 earthquakes in the past 40 years. When you ...
Carbon released from Earth's spreading tectonic plates, not volcanoes, may have triggered major transitions between ancient ...
The theory of Plate tectonics – developed from Alfred Wegener’s theory of Continental Drift to explain the movement of the continents – has become the prevailing theory underpinning our understanding ...
Researchers recently discovered a huge chain of extinct volcanoes buried deep below South China that formed when two tectonic plates collided during the breakup of Rodinia, around 800 million years ...
Natural disasters, from wildfires, floods and mudslides in western states to large earthquakes in Japan, have rocked, burned and flooded parts of the world in the first months of 2025. What’s next?
Researchers have examined tiny time capsules found in the oldest-known crystals in an attempt to settle a question that divides scientists: when did Earth’s tectonic plates begin to move? Plate ...
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 in the open access journal AGU ...

Volcanoes had lower greenhouse gas emissions in Earth's past
Eruptions from volcanic arcs, found where tectonic plates converge, are one of the major drivers of natural carbon emissions, ...
A new study introduces a novel way for tectonic plates — massive sheets of rock that jostle for position in the Earth’s crust and upper mantle — to bend and sink. It’s a bit of planetary Pilates that ...
