try to understand with help of diagrams.diagrams make it so easy that you can learn quickly.
use internet for explanations
use de blij to understand,though not so easy from here.
if still feel problem then you need proper guidance from a geography teacher.

however to learn in step wise first learn interanl structure ,then plates arrangement
then movements of plates
wich leads to earthquakes and
volcanism
see its easy
break down steps,one leading to another and make a chain

best of luck
