Earth's continents are slowly moving across the planet's surface due to plate tectonics, culminating in regions of crustal ...

Plate tectonics, or the recycling of Earth's crust, may have begun much earlier than previously thought—and may be a big ...

Emerging evidence suggests that plate tectonics, or the recycling of Earth's crust, may have begun much earlier than ...

The evolution and differentiation of the continental crust pose fundamental questions that are being addressed by new research concerning melting, melt extraction and transport through the crust, and ...

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 ...

For geologists, a continent is a large area of thick continental crust composed of granite or similar igneous rocks, forming the continental base, in combination with metamorphic rocks ...

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 ...

These movements have altered the positions and topography of the continents, contributing to the current state of the planet’s crust. While certain regions of the continental crust, known as ...
