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 ...

The movement of the plates creates three types of tectonic boundaries: convergent, where plates move into one another; divergent, where plates move apart; and transform, where plates move sideways ...

Large scale landforms at a destructive plate boundary include super volcanoes, such as the Campi Flegrei volcano in Italy - where the Eurasian plate and the African Atlantic plate are moving ...

Despite all the deep-sea expeditions and samples taken from the seabed over the past 100 years, humans still know very little ...

A large scale landform found along a conservative plate boundary is a fault line. One of the most active fault lines in the world is the San Andreas fault line in California, USA.

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 ...

For millions of years, Earth’s shifting plates have shaped continents, formed oceans, and built towering mountain ranges. But ...

Iceland’s volcanic activity is generally tame compared with explosive eruptions along the Pacific’s Ring of Fire. This time, it’s shaking up a town.

Plate tectonics is geology’s Theory of Everything. The realisation in the 1960s that Earth’s crust is made of fragments called plates—and that these plates can grow, shrink and move around ...

Four types of plate tectonic activity are demonstrated in this feature. Keep an eye on the map to see where in the world the activity takes place. Also known as spreading boundary, a divergent ...

This study out of the University of Houston points to a new theory that as North America began to split away, the Great Lakes ...

It has vast water oceans and abundant life. But Earth is also unique because it is the only planet with plate tectonics, which shaped its geology, climate and possibly influenced the evolution of ...
