What natural forces are created by plate tectonics?
Earthquakes and Volcanoes, sometimes tsunami's when the event is
offshore or close to a coast.
I also think Continental drift is accountable to this as well.
Hot spots caused by mantle plumes create new igneous rocks. Plate tectonics causes old crust to be destroyed and new crust to form which also forms new igneous rocks. Plate tectonics is also responsible for metamorphism which creates new metamorphic rocks. Sedimentary rocks are created by the weathering, erosion, and later lithification of of pre-existing rocks (e.g. sandstone). Sedimentary rocks can also precipitate from aqueous solutions (e.g. Halite). Forces: plate tectonics, weathering, erosion, precipitation
