Bookmark or Share- Introduction to plate tectonics (article) | Khan AcademyEarth’s lithosphere, or outermost shell, is broken up into large pieces called tectonic plates. These plates move slowly over the asthenosphere, a layer of softer rock below the lithosphere. On average, tectonic plates move a few centimeters per year. The place where two plates meet is called a plate boundary.
- Tectonics | Plate Boundaries, Earthquakes & Faults | BritannicaTectonics, scientific study of the deformation of the rocks that make up the Earth’s crust and the forces that produce such deformation. It deals with the folding and faulting associated with mountain building; the large-scale, gradual upward and downward movements of the crust (epeirogenic.
- Plate tectonics | Definition, Theory, Facts, & Evidenceplate tectonics, theory dealing with the dynamics of Earth’s outer shell—the lithosphere—that revolutionized Earth sciences by providing a uniform context for understanding mountain-building processes, volcanoes, and earthquakes as well as the evolution of Earth’s surface and reconstructing its past continents and oceans.
- Introduction to plate tectonics (video) | Khan AcademyAbout. Transcript. Earth's lithosphere is broken up into tectonic plates, which move slowly over time. Evidence like matching coastlines and same-species fossils on different continents support this. A plate boundary is where two tectonic plates meet. There are three types of plate boundaries: convergent, divergent, and transform.
- Earth's Shifting Tectonic Plates - National Geographic SocietyTectonic plates, the massive slabs of Earth’s lithosphere that help define our continents and ocean, are constantly on the move. Plate tectonics is driven by a variety of forces: dynamic movement in the mantle, dense oceanic crust interacting with the ductile asthenosphere, even the rotation of the planet.
