plates coming together, causes uplift and large scale mountain building, can cause volcanoes to form


a long, narrow area that has dropped between two faults

transform boundaries

plates grind past each other, causes mountain building


the transfer of thermal energy by the circulation or movement of a liquid or gas, happens in the mantle and drives plat moment


a geological process in which one edge of a crustal plate is forced sideways and downward into the mantle below another plate


formed when leading edge of plate subducts, usually in the ocean floor


The process by which Earth's crust breaks apart, can occur within continental crust or oceanic crust

magnetic reversal

the poles are always changing due to the crust always moving

oceanic crust

the portion of Earth's crust that is usually below the oceans and not associated with continental areas, thinner and higher in density that continental crust and basaltic rather than granitic in composition

continental crust

The portion of the earth's crust that primarily contains granite, is less dense than oceanic crust


break in earth's crust along which movement occurs


The point beneath Earth's surface where rock breaks under stress and causes an earthquake


the point on the Earth's surface directly above the focus of an earthquake

Alfred Wagner

Published the idea continental drift in 1904 and had emperical data


the supercontinent that was believed to exist in the mesezoic period


the outer layer of the Earth


the layer of the earth between the crust and the core, filled with plastid material


core and inner core, center of the earth
