4 Convergent BoundaryThe boundary formed by the collision of two lithospheric plates.
5 Divergent BoundaryThe boundary between two tectonic plates that are moving away from each other.
6 Transform BoundaryThe boundary between tectonic plates that are sliding past each other horizontally.
7 Possible causes of plate motion Scientists believe it is convection currents in the mantle that cause the tectonic plates to move.
8 Possible causes of plate motion, continued… They also believe it is a combination of “Ridge Push” and “Slab Pull”
9 G. P. S. Global Positioning System Technology that uses a network of satellites to map and locate points on the Earth’s surfaceScientist can use GPS to measure the rate at which the plates are moving
