Motion occurs when tectonic plates move sideways relative to one another. a. divergent b. transform c. convergent

Hey there!

Your correct answer would be . . . 



(transformed plates) are the plates that move right next to each other.
(divergent plates) move away from each other.
(convergent plates) move on top of each other.

So, from know this, transformed would be the correct answer.

Hope this helps.
