A new study co-led by a Cornell researcher has identified serpentinite – a green rock that looks a bit like snakeskin and holds fluids in its mineral structures – as a key driver of the oxygen recycli...
The existence of a tectonic plate named Resurrection has long been a topic of debate among geologists, with some arguing it was never real. Others say it subducted -- moved sideways and downward -- in...
Geophysicists funded by the National Science Foundation have reported that Earth's ever-shifting, underground network of tectonic plates was firmly in place more than 4 billion years ago -- at least a...
An enduring question in geology is when Earth's tectonic plates began pushing and pulling in a process that helped the planet evolve and shaped its continents into those that exist today. Some researc...
When the landmass that today is the Indian subcontinent slammed into Asia some 50 million years ago, the collision changed the configuration of the continents and altered global climate.Now a team of ...
No one can travel inside the earth to study what happens there. So scientists must do their best to replicate real-world conditions inside the lab.“We are interested in large-scale geophysical process...
A microplate discovered off the west coast of Ecuador adds another piece to Earth’s tectonic puzzle, according to Rice University scientists.Researchers led by Rice geophysicist Richard Gordon discove...

Plate tectonics, the idea that the surface of the Earth is made up of plates that move apart and come back together, has been used to explain the locations of volcanoes and earthquakes since the 1960s...
The puzzle pieces of tectonic plates that make up the outer layer of the earth are not rigid and don't fit together as nicely as we were taught in high school.
23 March 2007,A 3.8 billion-year-old sequence of rocks from Greenland is helping scientists pinpoint when the Earth's plate tectonics system kicked into gear, according to new research in the 23 March...
