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 ...

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, ...

With tectonic plates bumping and grinding against each other, Earth is a pretty active planet. But when did this activity begin? A new study from Yale University claims to have found evidence that ...

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 ...

FILE - A girl looks at the moon through a telescope in Caracas, Venezuela, on Sunday, May 15, 2022. The best day to spot five planets, Mercury, Jupiter, Venus, Uranus and Mars, lined up in the night ...

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 ...

The Earth's outer layer is made up of a series of moving, interacting plates whose motion at the surface generates earthquakes, creates volcanoes and builds mountains. Geoscientists have long sought ...

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 ...

The research reveals how one of Earth’s defining geologic features likely formed — and set the stage for the emergence of life Abigail Eisenstadt Zircons are the oldest minerals in the world and come ...

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 deep-seated ...
