Answer:
As a stone inside a tree, I’ll help your words outlive thee. But if you push me as I stand, the more I move the less I am.
I pass before the sun, yet make no shadow. I'm all around you, but you cannot see me. What am I?
With a halo of water and a tongue of wood, stone as skin long I stood. What am I?
I have a name that's not mine and no one cares about me in their prime. People cry at my sight and lie by me all day and night.
I am a precious stone, as clear as a diamond. Though you can walk on water with my power, try to keep me, and I'll vanish in an hour. What am I?
What is lighter than what it is made of?
