Scientists have discovered a new layer of partly molten rock under the Earth's crust that might help settle a long-standing debate about how tectonic plates move. Researchers had previously identified ...

Map of Earth's principal tectonic plates. Earth's lithosphere. Major and minor plates. arrows indicate direction of movement at plate boundaries. Vector illustration. Billions of years ago, Earth's ...

Scientists have been trying to solve the mystery of why plate tectonics works the way it does for over a hundred years. And they might have just uncovered a key to cracking it. Eons is available to ...

The Earth’s crust is made of pieces call the tectonic plates. These plates move and shift and change to the face of the planet. How do they move and how fast? Science Trek is available to stream on ...

Earth is estimated to be 4.5 billion years old, but understanding when it evolved from a sizzling hot ball to a planet that could host life is a little more difficult. Earth is estimated to be 4.5 ...

Researchers have detected a previously unknown layer of partially molten rock beneath Earth’s crust. The discovery could help scientists learn more about the movements of Earth’s tectonic plates, ...

ANN ARBOR—As anyone with a smattering of geological knowledge knows, Earth’s crust is made up of plates that creep over the planet’s surface at a rate of several inches per year. But why do they move ...

The activity of the solid Earth – for example, volcanoes in Java, earthquakes in Japan, etc – is well understood within the context of the ~50-year-old theory of plate tectonics. This theory posits ...

Examining how plates move in Earth's mantle and how mountains form is no easy feat. Certain rocks that have sunk deep into Earth's interior and then returned from there can deliver answers. Examining ...

Our planet has an outer layer made up of several plates, which move relative to one another. While we may take this knowledge for granted, this theory of plate tectonics was only formulated in the ...

In the heart of Asia, deep underground, two huge tectonic plates are crashing into each other — a violent but slow-motion bout of geological bumper cars that over time has sculpted the soaring ...
