sources of plate motion
the motion of earth's tectonic plates is due in part to convection, as well as to ridge push and slab pull. convection is a motion in a fluid or plastic material caused by heating material below and cooling material above.
create a model that shows plate motion and its sources. draw a side-view of tectonic plate motion and two convection currents in the mantle to form trenches and a mid ocean ridge. use arrows to represent the direction of the convection currents. identify trenches and ridges in the crust. identify ridge push and slab pull in the illustration. draw your model here or attach it with your assignment for submission.
