Record evidence for interactions between tectonic plates.
As you explore the lesson, gather
evidence to help explain landforms
and geological processes that occur
along plate boundaries and the
processes that drive plate motion.

Imagine that someone pushes one marble toward a motionless marble. would there still be action-reaction forces involved in the collision? how might the marbles’ motions be changed? ?
