Plate tectonic refers to the geological processes that underlie the formation of mountains. These processes are associated with large-scale movements of the earths. Folding, faulting, volcanic activity, igneous intrusion and metamorphism are all parts of the orogenic process of mountain building.
Tectonics movement also important in changing the stability of earth crust in term of changing location of coastlines. How plate tectonic will effect marine and coastal resources.
