The movement of the plates creates three types of tectonic boundaries: convergent ... the highest mountain system on Earth. As the mash-up continues, the mountains get higher.

With an underlying universal theme of convection, a new textbook introduces upper-level geology, geophysics, physics, and engineering students to the geophysics behind the Earth System.

The study also provides a new approach to solving one of the biggest enduring scientific mysteries: when did plate tectonics ...

Researchers have made a new discovery that changes our understanding of Earth's early geological history, challenging beliefs ...

Plate tectonics is the theory that Earth's outer layer is made up of plates, which have moved throughout Earth's history. The theory explains the how and why behind mountains, volcanoes ...

According to plate tectonics theory, Earth's outer shell is divided into multiple plates that slowly glide over the mantle. This slowly changes Earth's surface over time by merging, or separating ...

"It's like a lid on top of its convective mantle." But without any other nearby planets exhibiting plate tectonics to compare Earth's system to, it's hard to know precisely what causes a planet to ...

To the Ends of the Earth: The Natural World - Pushing Boundaries is available to stream on pbs.org and the free PBS App, available on iPhone, Apple TV, Android TV, Android smartphones, Amazon Fire ...
