1 Οκτ 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 (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.
1 Οκτ 2018 · Evidence from the rock record indicates that the modern episode of plate tectonics began in Neoproterozoic time. A Neoproterozoic transition from single lid to plate tectonics also explains kimberlite ages, the Neoproterozoic climate crisis and the Neoproterozoic acceleration of evolution.
14 Αυγ 2024 · Although many uncertainties remain, the history of plate tectonics is finally coming into view. Hidden history. Since the 1960s, geoscientists have recognized that Earth’s outer shell — the...
13 Ιαν 2021 · Plate tectonics describes how Earth’s entire, 100-kilometer-thick outermost layer, called the lithosphere, is broken into a jigsaw puzzle of plates — slabs of rock bearing both continents and...
1 Οκτ 2024 · In 1912 German meteorologist Alfred Wegener, impressed by the similarity of the geography of the Atlantic coastlines, explicitly presented the concept of continental drift. Though plate tectonics is by no means synonymous with continental drift, the term encompasses this idea and derives much of its impact from it.
Earth’s crust is divided into shifting tectonic plates. The forces behind plate tectonics play a part in determining nearly everything about Earth, from its climate to the evolution of life.
