Tectonics(fromLatintectonicus; fromAncient Greekτεκτονικός(tektonikos), meaning 'pertaining tobuilding'[1]) is the process that controls the structure and properties of the Earth's crust and its evolution through time. In particular, it describes the processes ofmountain building, the growth and behavior of the strong, old cores of continents known ascratons, and the ways in which the relatively rigidplatesthat constitute the Earth's outer shell interact with each other. Tectonics also provides a framework for understanding theearthquakeandvolcanic beltsthat directly affect much of the global population. Tectonic studies are important as guides foreconomic geologistssearching forfossil fuelsandore depositsof metallic and nonmetallic resources. An understanding of tectonic principles is essential togeomorphologiststo explainerosion patternsand other Earth surface features.
