What are Plate Tectonics?
What are Plate Tectonics? In other words, Earth's lithosphere is just an external shell of Earth which has enormous slabs floating on a fluid asthenosphere beneath that contains tectonic plates. Major ones include the Pacific Plate and the Eurasian Plate besides the much smaller Philippine plate. Minor lithospheric plates are what split the Earth. These plates constantly shift owing to convective currents within the mantle, which are circulating heat from the core of the Earth, and they drift, collide, separate, or slide past one another at the edges known as the plate margin. It is this movement, known more broadly as plate tectonics, which has made the Earth's surface dynamic: mountains with it through moving plates, and deep trenches carved into the sea and volcanoes with their eruptions, the entire scope of these has proved enormously influential, alike both to natural ecosystems and the human societies. There are three types of plate boundaries associated with certain ge...
