Be sure to watch GMSA@9 on Wednesdays, when KSAT Meteorologist Sarah Spivey demonstrates and explains the science behind it.

Some great ideas shake up the world. For centuries, the outermost layer of Earth was thought to be static, rigid, locked in place. But the theory of plate tectonics has rocked this picture of the ...

Inside most of the Earth, olivine is a hot mineral whose creepy behavior drives plate tectonics. In the upper mantle — the top of the planetary layer between the crust and core — olivine's unusual ...

(Inside Science) — Shifting, slipping and colliding tectonic plates played an essential role in the emergence and evolution of life on Earth. Such tectonic activity generated volcanoes that spewed ...

The cycling of water within Earth's interior regulates plate tectonics, volcanism, ocean volume, and climate stability, ...

With tectonic plates bumping and grinding against each other, Earth is a pretty active planet. But when did this activity begin? A new study from Yale University claims to have found evidence that ...

A hidden chunk of an ancient tectonic plate is stuck to the Pacific Ocean floor and sliding under North America, complicating earthquake risk at the Cascadia subduction zone.

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.

Freelance writer Amanda C. Kooser covers gadgets and tech news with a twist for CNET. When not wallowing in weird gear and iPad apps for cats, she can be found tinkering with her 1956 DeSoto. Carole ...

A new paper has revealed that tectonic activity on this planet—a unique feature in the solar system—could have been spurred by a stream of asteroid impacts. Previously, computer models have shown that ...

Researchers examined some of the oldest rocks in western Greenland. This is an Inside Science story. (Inside Science) -- Scientists believe the way the Earth's tectonic plates began shifting and ...

When plate tectonics emerged in the 1960s it became a unifying theory, “the first global theory ever to be generally accepted in the entire history of earth science,” writes Harvard University science ...
