B. Weak acid breaks down minerals by reacting with them.

C. An animal kicks a rock down a hill where it falls, hits another rock, and shatters.

E. Plant roots grow and split the rocks into pieces.

a=c and then d= c because of the band so you get ac/dc and you add them together you get sound waves
