Earthquakes occur when the rock on one side of a fault slips relative to the other. The fault surface can be vertical, ...

Earth's lithosphere — its crust and rigid upper mantle — is split into roughly 15 constantly-moving plates. These plates are perpetually shifting, colliding and pulling apart from one another.

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 Earth is made up of different layers: Therefore, instead of tectonic plates moving because of the convection currents, evidence suggests it is the plates that drive the convection. Slab pull ...

Surprising differences in the two so-called Large Low-Velocity Provinces may risk instability in Earth's protective magnetic ...

The two continent-sized provinces have been known since the 1970s, but it’s only in the last few years we’ve started to ...

Different elements are present in different parts of the Earth’s structure. The crust is made from enormous plates which move very slowly due to movements of the mantle below. The Earth's structure.

South Carolina has high seismic activity despite not being on a plate boundary. Scientists still don't know the answer for ...

India charged across the equator at rates of up to 15 cm/year, in the process closing ... The continents are carried by the Earth's tectonic plates like people on an escalator.

Plate tectonics describes the giant “plates” of crust that slowly move around Earth’s surface over hundreds of millions of years; it not only produces new rocks at volcanoes where the plates are ...

Scientists have revealed that two continent-size regions in Earth's deep mantle have distinctive histories and resulting chemical composition, in contrast to the common assumption they are the same.
