Until recently, researchers believed only one planet in our solar system had plate tectonics: Earth. But in a recent study, Brown University researchers used atmospheric modeling to show that Venus, ...

Plate tectonics, or the shifting of plates across a planet or moon, may be the key to lifeforms developing as an advanced species. And the rarity of plate tectonics elsewhere in the universe may be ...

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 ...

Venus, may have once had tectonic plate movements similar to those believed to have occurred on early Earth, a new study found. The finding sets up tantalizing scenarios regarding the possibility of ...

Long ago, Earth's outer shell cracked into pieces, which we now call tectonic plates. In a new study, scientists investigated the origins of plate tectonics and found its history rooted in Earth.

Some 4.5 billion years ago, a Mars-sized object smashed into the nascent Earth, spinning off our moon. Now a team of scientists proposes this giant impact did even more: The collision left behind ...

Scientists may have discovered the world's oldest arc-slicing fault in Northwestern Australia's remote deserts. The finding demonstrates that plate tectonic processes were operational at least 3 ...

Earth's crust today has a surprisingly similar composition to the planet's first outer shell, or "protocrust," new research finds. This early rocky shell featured chemical signatures previously ...

RENO, Nev. – 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. A study published in the ...

Tectonic map of the Earth. The first continental crust on Earth formed more than 3 billion years ago. Likely the first fragments formed by partial melting and re-crystallization of the primordial ...

CHAMPAIGN, Ill. — The Andes Mountains are much taller than plate tectonic theories predict they should be, a fact that has puzzled geologists for decades. Mountain-building models tend to focus on the ...
