Answer:
No matter how little or how much you use me, you change me every month.
I have roots nobody sees. I am taller than trees. Up up I go but I never grow.
Some try to hide, some try to cheat, but time will show we always will meet.
Bright as diamonds, loud as thunder, never still, a thing of wonder. What am I?
I am the place to turn when nature calls.
I go in hard come out soft. Blow me hard and I’ll make a pop.
