Reasons to move a pawn

1.Candidate passed pawns should lead. So with pawns a b and c vs. a and b with white to move then c4! is likely best. Of course king positions matter too.
2.The opponent has opposition and you use a pawn move as a reserve tempo to elbow through.
3.Pawn breakthrough (giving the opponent many more pawns but it doesn't matter usually since your new queen will clean them up)
4.Control the center.
5.Establishing a secure outpost for a piece (such as a knight)
6.Making way for a piece (such as sacrificing a pawn on e5 so a knight can jump to e4).
7.Opening lines.
8.Dynamically activating your pieces (such as exchanging an isolated d-pawn with d5 and usually the e6 pawn recaptures and then knight recaptures)
9.Pawn storm against a king.
10.Prophylaxis (such as playing g3 so a Nh5 can' jump to f4 tying a bishop to the defense of the g-pawn).
11.Fortressing.
12.Sacrificing so the opponent's pawn gets in the king's own way (I'm recalling a puzzle from Dvoretsky's Endgame Manual and Secrets of Pawn Endings here).
can anybody help with with this. i have to give reasons why to move a pawn, as a little challenge.

take control of the centre
attack an enemy piece
free up pieces to move
ETC
