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 ...

Microscopic zircon crystals discovered in Western Australia suggest that Earth may have had continental crust as early as 4.4 billion years ago, millions of years earlier than previously thought. For ...

A study on tectonic plates that converge on the Tibetan Plateau has shown that Earth's fault lines are far weaker and the ...

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

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 ...

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.

It turns out that continental breakups are just as messy as human ones, with the events leaving fragments scattered far from home ...

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 ...

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 ...

The Andes Mountains are much taller than plate tectonic theories predict they should be, a fact that has puzzled geologists for decades. Mountain-building models tend to focus on the deep-seated ...

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 ...
