![]() ![]() Plate tectonics is a relatively young scientific theory that needed the advancement of observational and computing technology in the 1950s and 1960s to become fully elaborated. Plate Tectonic Theoryīeyond merely describing current plate motions, Plate Tectonics provides an overarching framework that connects many elements of Earth science. Plate tectonics has important implications for our understanding of natural hazards, climate change, and the evolution of life on Earth. Some of the key concepts related to plate tectonics include the types of plate boundaries, the processes of subduction and sea-floor spreading, the formation of mountains and oceanic ridges, and the distribution of earthquakes and volcanic activity around the world. It replaced earlier theories of “continental drift” and “sea-floor spreading” and provided a unifying framework for understanding the Earth’s geological history and the distribution of natural resources. The theory of plate tectonics was developed in the 1960s and 1970s, based on a combination of geophysical data and observations of the Earth’s surface features. As these plates move, they interact with each other, leading to a wide range of geological phenomena, such as earthquakes, volcanic eruptions, and the formation of mountain ranges. ![]() The theory proposes that the Earth’s lithosphere is broken into a series of plates that are in constant motion, driven by the heat generated from the Earth’s core. Plate tectonics is a scientific theory that explains the movements and behaviors of the Earth’s lithosphere, which is composed of the crust and uppermost mantle.
