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.

Have tectonic plates changed speed over the last 3 billion years? The answer has far-reaching implications, as plate tectonics affected everything from the supply of vital nutrients for early life to ...

The emergence of plate tectonics in the late 1960s led to a paradigm shift from fixism to mobilism of global tectonics, providing a unifying context for the previously disparate disciplines of Earth ...

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 ...

Researchers analyzing ancient deposits in Australia found evidence that Earth's layers started to get mixed up — a fingerprint of plate tectonics — about 1.3 billion years after the planet formed.

An artistic cross section of the Earth’s outer shell showing the effect of plate tectonics on the surface. Volcanoes form above the place where plates slide – or subduct – over one another.

Earth’s surface is constantly shifting, shaped by the slow but powerful movement of tectonic plates. While some plates have ...

A massive collision between the Indian tectonic plate and the Eurasian tectonic plate is causing the Himalayas to grow, but new research suggests it might also be ripping Tibet apart. According to new ...

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 ...
