Plate Tectonics - National Geographic Society
WEBMar 7, 2024 — Plate tectonics is a scientific theory that explains how major landforms are created as a result of Earth’s subterranean movements. The theory, which solidified in the 1960s, transformed the earth sciences by explaining many phenomena, including mountain building events, volcanoes, and earthquakes. In plate tectonics, Earth’s …
Plate tectonics | Definition, Theory, Facts, & Evidence
WEBSep 10, 2024 — plate 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.
Plate tectonics - Wikipedia
WEBPlate tectonics (from Latin tectonicus, from Ancient Greek τεκτονικός (tektonikós) 'pertaining to building') [1] is the scientific theory that Earth's lithosphere comprises a number of large tectonic plates, which have been slowly moving since 3–4 billion years ago.
Plate Tectonics: Definition, Theory, Types, Facts, & Evidence
WEBFeb 17, 2023 — What are Tectonic Plates. Tectonic plates are large, irregular-shaped slabs of rock making up the Earth’s crust and upper mantle. They are found to float on top of a semi-liquid layer of rock called the asthenosphere.
Plate Tectonics - Understanding Global Change
WEBThe theory of plate tectonics explains processes in the geosphere that are fueled by Earth’s internal heat that have operated over billions of years. These changes can be imperceptible over a human lifetime or violent and abrupt, and continue to …
Theory of plate tectonics | Britannica
WEBplate tectonics, Theory that the Earth’s lithosphere (the crust and upper portion of the mantle) is divided into about 12 large plates and several small ones that float on and travel independently over the asthenosphere.
Plate Tectonics Theory, Diagrams, Boundaries - Geology.com
WEBPlate tectonics is a theory about how Earth's lithosphere is divided into a series of rigid plates; and, how movements of these plates produce earthquakes, volcanoes, ocean trenches, mountain ranges, and more.

Plate Tectonics - National Geographic Society
WEBThe Earth’s crust is broken up into a series of massive sections called plates. These tectonic plates rest upon the convecting mantle, which causes them to move. The movements of these plates can account for noticeable geologic events such as earthquakes, volcanic eruptions, and more subtle yet sublime events, like the building of …
Earth sciences - Plate Tectonics, Geology, Geophysics
WEBJul 29, 2024 — Plate tectonics describes seismic activity, volcanism, mountain building, and various other Earth processes in terms of the structure and mechanical behaviour of a small number of enormous rigid plates thought to constitute the outer part of the planet (i.e., the lithosphere).
