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 emergence of plate tectonics in the late 1960s led to a paradigm shift from fixism to mobilism of global tectonics, providing a unifying context for the previously disparate disciplines of Earth ...

The solid ground that we all live on forms a thin crust around the Earth. It’s no more than 50km thick - and it’s just the upper part of the lithosphere. Below it is the upper mantle. It’s mostly ...

Plate tectonics is the theory used to explain the structure of the Earth’s crust and many of the associated phenomenon. The rigid lithosphere is split into 15 major plates that slowly move on top of ...

It’s right there in the name: “plate tectonics.” Geology’s organizing theory hinges on plates—thin, interlocking pieces of Earth’s rocky skin. Plates’ movements explain earthquakes, volcanoes, ...
