The movement of the plates creates three types of tectonic boundaries ... These convergent boundaries also occur where a plate of ocean dives, in a process called subduction, under a landmass.

The finding demonstrates that plate tectonic processes were operational at least 3 billion years ago, fueling the ongoing ...

A fascinating new study reveals how two of Earth’s established continents may constitute one whole landmass in itself.

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 ...

Plate boundaries are where the action ... students use scientific data to learn how the scientific process works. They learn where the Earth's tectonic plates and their boundaries are, what ...

Plate tectonics give rise to Earth's mountain ranges, earthquakes and the long-term movement of continents, and may even have provided the right conditions for life on Earth. But as far as we know ...

The mid-ocean ridges mark the lines along which the Earth is turning itself inside out through the process of plate tectonics. Advances in technology are helping to reveal the intricate details of ...

Plate tectonics is relatively new, put forth in the last 30 years or so — its forerunner was the now-discarded continental drift theory. The theory states that Earth's outer shell is made up of ...

The Earth is made of different layers: the core, mantle and crust. Plate tectonic theory shows that the crust of the Earth is split into plates (pieces of the Earth’s crust). The movement of ...
