Easy poems riddles

You bury me when I am alive, and dig me up when I die. What am I?

Until I am measured I am not known. Yet how you miss me when I have flown.

Only one color, but not one size. Stuck at the bottom, yet I easily fly. Present in sun, but not in rain. Doing no harm, and feeling no pain. What Am I?
