Plate boundaries are where the action is. A large fraction of all earthquakes, volcanic eruptions, and mountain building occurs at plate boundaries. It is also where most of the people on Earth live.

The diagram below shows the structure of the earth. In geography, taking a slice through a structure to see inside is called a cross section. Continental plates are usually quite thick (between 35 to ...

Craig O'Neill receives funding from the ARC. Plate tectonics may be a phase in the evolution of planets that has implications for the habitability of exoplanets, according to new research published ...

The initiation of plate tectonics on Earth is a critical event in our planet’s history. The time lag between the first proto-subduction (about 4 billion years ago) and global tectonics (approximately ...

Earth's surface is broken up into large plates that rub against each other, causing earthquakes, volcanoes and large mountain ranges. But how unique is our planet's geology? When you purchase through ...

As we’ve explored the Solar System, some items we’re familiar with from Earth’s geology have kept appearing in new places. Glaciers, volcanoes, and geysers have all been found on other planets and ...

From the deepest ocean trench to the tallest mountain, plate tectonics explains the features and movement of Earth's surface in the present and the past. The theory of plate tectonics was developed ...
