Plate Tectonics
Plate tectonics is the scientific theory that Earth's outer layer, or lithosphere, is divided into large plates that float on the semi-fluid asthenosphere beneath. These tectonic plates constantly move, causing earthquakes (seismology), volcanic eruptions (volcanology), and mountain formation. By studying gravity variations (gravimetry), scientists can understand plate interactions. Tectonophysics investigates the forces involved in plate movements, while paleomagnetism examines past magnetic records in rocks to track plate shifts. Together, these fields help explain how Earth's surface evolves and responds to dynamic geological processes.

Plate tectonics is the scientific theory explaining how Earth's surface is made up of large, moving pieces called tectonic plates. These plates float on the semi-fluid mantle beneath them. Their movement causes geological events like earthquakes, volcanic eruptions, and mountain formation. Plates can converge, diverge, or slide past each other, each interaction shaping our planet’s landscape over millions of years. Understanding plate tectonics helps us comprehend natural phenomena and informs building practices in earthquake-prone areas, providing insight into Earth's dynamic processes and the history of its formation.
