What is the theory of plate tectonics?
The theory of plate tectonics gives us probable evidences about the formation of various physical features on the earth. According to this theory, there are seven major and some minor tectonic plates. The movement of these tectonic plates has resulted not only in the change of position and size of many continents but also the evolution and the change in various landforms over a period of time. For example, the Himalayas were formed due the movements of the tectonic plates.
