A seamount sitting on a subducting tectonic plate off the coast of Japan and plowing its way into Earth's mantle may be at the root of several magnitude 7 earthquakes in the past 40 years. When you ...

Add Yahoo as a preferred source to see more of our stories on Google. Scientists have developed a new model of Earth’s tectonic plates that provides fresh insights into the planet’s geological history ...

The Earth's mantle might not always move along in lockstep with the overlying tectonic crust—as set out in science textbooks for decades—but may instead behave differently. This is the conclusion of ...

Magnetic crystals provide the earliest evidence yet of the plate tectonics that likely made Earth habitable, pushing its ...

Plate tectonics is not just about earthquakes and volcanoes. It is deeply connected to the conditions that made life possible ...

A volcano is an opening in the Earth's crust that allows molten rock, gases, and debris to escape from below the surface. The ...

We often affiliate plate tectonics with earthquakes, as we are all taught in school that the shifting of plates leads to big shakes. But plate tectonics serve a far more important job to the planet ...

Some of the world’s volcanic hot spots may be fueled by molten material that originates surprisingly close to Earth’s surface. While some of the hottest spots are fueled by plumes of buoyant material ...

At subduction zones, the force of gravity drags dense tectonic plates beneath other, more buoyant plates. As the plates slide past one another, stress builds and is eventually released in the largest ...
