The movement of the plates creates three types of tectonic boundaries ... boundaries also occur where a plate of ocean dives, in a process called subduction, under a landmass.

A reappraisal of decades-old data suggests that strange circular formations on Venus could be volcanic “rings of fire” ...

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 ...

In this lesson, students use scientific data to learn how the scientific process works. They learn where the Earth's tectonic plates and their boundaries are, what happens at the boundaries ...

Vast, quasi-circular features on Venus's surface may reveal that the planet has ongoing tectonics, according to new research ...

Venus, often written off as a geologically dead world, is far more active beneath its blistering surface than previously ...

New details about the crust on Venus include some surprises about the geology of Earth's hotter twin, according to new ...

NASA researchers have discovered evidence of tectonic activity on Venus by re-examining decades-old radar data. The findings ...

Scientists have uncovered one of the most exciting geological discoveries of the decade – the long-lost Pontus tectonic plate. This ancient “mega plate,” which once spanned an astonishing 15 million ...

Yet pinpointing the origins of this fundamental process remains a contentious debate. Related: Earth's plate tectonics fired up hundreds of millions of years earlier than we thought, ancient ...

Experts say portions of the continent are pulling apart, creating the possibility that the Horn of Africa will become an ...

Venus has a crust that is all one piece, with no evidence of subduction caused by plate tectonics like on Earth.
