How does the plate tectonic theory explain mountain belt formation?
Plate Tectonic Theory Formulated during the 1960’s, the Plate Tectonic Theory is widely accepted among geologists. Plate tectonics describes motions of the Earth’s crust and mantle. The fractures divide the brittle layers on the Earth’s surface which forces in hot interior which moves the plates. The shift and movements of the plates are considered one of the main causes for geological events. They have raised mountains, open and closed basins in the ocean, influenced evolution, and is a cause of volcanoes and earthquakes. Mountain Belt Formation The thickening of the Earth’s crust is considered the formation of the mountain belt. The mountain belts are typically formed due to plate tectonic activity. When the plates collide they crumple and stick together or are sutured together. The process that produces the mountain building is called orogenesis, which include; Folding (anticlines & synclines), thrust faulting, metamorphism, and igneous activity.
