Plate tectonics - Wikipedia
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.
7 Major Tectonic Plates: The World’s Largest Plate Tectonics
Earth’s tectonic plate boundaries are unusual because they can consist of continent and ocean crust. Here are the 7 major tectonic plates of the world in a bit more detail. 1. Pacific Plate. The Pacific major plate is the largest which underlies the Pacific Ocean.
List of tectonic plates - Wikipedia
This is a list of tectonic plates on Earth's surface. Tectonic plates are pieces of Earth's crust and uppermost mantle, together referred to as the lithosphere.
Plate Tectonics Map - Plate Boundary Map - Geology.com
A map of the tectonic plates of the earth showing the different boundary types in different colors. Locations where plates collide (convergent boundaries) are shown in red. Locations where plates are spreading (divergent boundaries) are shown in yellow.

2024年12月5日 · 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: Definition, Theory, Types, Facts, & Evidence
2023年2月17日 · 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 tectonic theory began in 1915 when Alfred Wegener proposed his theory of continental drift.

2023年10月19日 · Geologists studying the Earth use scientific observation and evidence to construct a picture of what the Earth looked like at different periods in the geologic past. Use this map gallery to better understand how plate tectonics created the ocean and continents we are familiar with today.
