The theory of Plate tectonics – developed from Alfred Wegener’s theory of Continental Drift to explain the movement of the continents – has become the prevailing theory underpinning our understanding ...

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 ...

Earth’s crust looks solid from the surface, but it is broken into a shifting mosaic of slabs that slowly rearrange oceans and continents. Understanding how those tectonic plates first formed is one of ...

SIOUX CITY (KTIV) - Gather your supplies! In this episode we will use everyday materials to learn about tectonic plates and fault lines. A subduction fault is when two plates have different densities.

Researchers used small zircon crystals to unlock information about magmas and plate tectonic activity in early Earth. The research provides chemical evidence that plate tectonics was most likely ...

Earth’s crust may have gone on the move roughly 3.8 billion years ago. “Earth is actually quite distinct to other planets, in that it has plate tectonics,” says study coauthor Nadja Drabon, a ...

A new study of rocks that formed billions of years ago lends fresh insight into how Earth's plate tectonics—the movement of large pieces of Earth's outer shell—evolved over the planet's ...

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.

Scientists studying rocks in South Africa report evidence for the earliest known earthquake triggered by plate tectonics. The temblor struck more than 3 billion years ago. The rocks preserve telltale ...

William R. Dickinson, a leader in the “plate tectonics revolution” that re-formed our view of how geological forces transform Earth, died last week while on an archaeological field trip to Tonga. He ...
