In 2021, geologists animated a video that shows how Earth's tectonic plates moved over the last billion years. The plates move together and apart at the speed of fingernail growth, and the video ...

Tectonic plates are massive slabs of solid rock that make up Earth’s outer layer, known as the lithosphere. These plates float on the semi-fluid layer beneath them called the asthenosphere. Earth’s ...

New findings provide a greater understanding of plate subduction, or how tectonic plates slide beneath one another. This recycling of surface materials and volatile elements deep into the Earth's ...

Mastermind geologists have reverse-engineered Earth's missing tectonic plate. Tectonic activity determined how continents form and how today's Earth was made. The researchers unfolded and untucked ...

For millions of years, Earth’s shifting plates have shaped continents, formed oceans, and built towering mountain ranges. But ...
