tectoniske

Tectonics, also known as plate tectonics, is the scientific theory that describes the large-scale motions of Earth's lithosphere. The lithosphere is divided into several large plates that move relative to one another, driven by convection currents in the underlying asthenosphere. These plates interact at their boundaries, where they converge, diverge, or slip past each other. Convergent boundaries occur when two plates move towards each other, resulting in either subduction (one plate sliding beneath the other) or continental collision. Divergent boundaries occur when two plates move away from each other, creating new crust at mid-ocean ridges. Transform boundaries occur when two plates slide past each other horizontally. The movement of these plates is responsible for various geological phenomena, including earthquakes, volcanic activity, and the formation of mountain ranges. The theory of plate tectonics was developed in the 1960s and has since become a fundamental concept in geology, explaining the distribution of earthquakes, volcanoes, and mountain ranges around the world.
