Earth's surface is a turbulent place. Mountains rise, continents merge and split, and earthquakes shake the ground. All of these processes result from plate tectonics, the movement of enormous chunks ...
Ancient plate tectonics in the Archean period differs from modern plate tectonics in the Phanerozoic period because of the higher mantle temperatures inside the early Earth, the thicker basaltic crust ...
The process of plate tectonics may be driven by convection in Earth’s mantle, the pull of heavy old pieces of crust into the mantle, or some combination of both.
The theory of plate tectonics revolutionized the earth sciences by explaining how the movement of geologic plates causes mountain building, volcanoes, and earthquakes.
Tectonics is the study of the plates, the forces acting on them, and their motion. NASA has a variety of tectonic data from an assortment of sources, such as synthetic aperture radar instruments and global positioning systems.

Plate tectonics is a scientific theory that explains the structure and dynamics of the Earth’s lithosphere, which is divided into several major and minor tectonic plates. These plates are in constant motion due to the heat from the Earth’s interior, leading to various geological phenomena. The theory elucidates the formation of earthquakes, volcanoes, and mountain ranges, as well as the ...
Plate tectonics thus provides “the big picture” of geology; it explains how mountain ranges, earthquakes, volcanoes, shorelines, and other features tend to form where the moving plates interact along their boundaries.
