Detailed explanation-1: -Plate tectonics has made good predictions that have come true. Good theories are able to explain a multitude of different kinds of data. Plate tectonics explains the locations of earthquakes, volcanos and mid ocean ridges. Plate tectonics explains the formation of mountains and continents.
Detailed explanation-2: -The system of ideas behind plate tectonics theory suggests that Earth’s outer shell (lithosphere) is divided into several plates that glide over the Earth’s rocky inner layer above the soft core (mantle). The plates act like a hard and rigid shell compared to Earth’s mantle.
Detailed explanation-3: -Plate tectonics is considered a “unifying theory” in the field of geology because it synthesizes the work and theories of most other areas of geology (Oreskes and LeGrand 2003). The generation of mountains, deep-sea trenches, volcanic chains, island arcs, and rift valleys can be explained by plate motions.
Detailed explanation-4: -Plate tectonics thus provides “the big picture” of geology; it explains how mountain ranges, earthquakes, volcanoes, shorelines, and other features tend to form where the moving plates interact along their boundaries.
