The Plate Tectonic Theory is a major theory in global tectonic system that revolutionized our understanding of Earth's dynamic processes. This comprehensive theory explains the formation of mountains, occurrence of earthquakes and volcanoes, and the continuous movement of continents. It represents a significant advancement influenced by quantitative revolution, positivism, and system analysis in physical geography. What is Plate Tectonic Theory? The Plate Tectonic Theory (PTT) is a major theory in global tectonic system influenced by quantitative revolution, positivism, and system analysis in physical geography. The term "plate" was given by Wilson, Morgan, and Mackenzie . The plates are solid lithospheric slabs which slide on elastic/plastic asthenosphere . Lithosphere = Crust + Upper Mantle These plates experience continuous horizontal and vertical movement which causes deformation of rock on the Earth's crust or crustal ...
