I believe the word that does not fit is thermal. oceans are full of water (obviously) they're deep, which could be considered expansion, but there is no other word to connect to thermal. I hope this makes sense
I'm not sure what you mean by alteration but if you mean alliteration which mean the repeating of the same first letter, then that would be <u>flickering flame</u> but if you don't mean that then I can't help, I hope you got your answer
