Title: What are some noncyclic changes that occur on earth? Post by: LessieP on Sep 23, 2012 The question is originally says "Some changes that occur on Earth are cyclic- they occur over and over again at regular intervals. List two changes that occur on a regular basis and can be considered cyclic and two changes that are not cyclic." I already have the cyclic changes- tides and seasons, but I'm stuck on the noncylic... Everything seems to be cyclic...
