 * scientific theory-** a well-tested concept that explains a wide range of observations
 * plate tectonics-** a theory that states pieces of earth's lithosphere are in constant, slow-motion, driven by convection currents in the mantle
 * faults-** breaks in earth's crust where rocks have slipped past each other
 * transform boundary-** a place where two plates slip past each other, moving in opposite directions
