Some areas of continental crust have maintained long-term stability from the beginning of Earth's history, with little destruction by tectonic events or mantle convection, known as cratons.

the oldest sections of the continental crust are breaking apart. Scientists have argued that the Earth’s crust has shifted to change its positions as well as the terrain of the Earth.

Continental and oceanic plates all fit together to form the outer crust of the planet. Eight major plates are named on the diagram below. Heat from the core makes magma in the mantle rise towards ...

New crust is continually being pushed away from divergent boundaries (where sea-floor spreading occurs), increasing Earth's surface. But the Earth isn't getting any bigger. What happens ...
