In this essay, we will be discussing plate tectonics and its types. Plate tectonics is the scientific study of the movements and dynamics of Earth's lithosphere, that is, the crust and upper mantle. This theory was first proposed in the early 20th century by German meteorologist Alfred Wegener. The Earth's lithosphere is divided into several large plates that move around on the planet's surface. Earthquakes, volcanoes, and mountain building are all a result of these plate motions. There are three main types of plate boundaries: divergent, convergent, and lateral.
