What Am I?

I'm falling!  I'm falling!  I'm falling! 
I hope when I hit that rock I won't splatter all over the place!
I'm glad it's 32 below or I won't survive long!
Oh, no!  that human wants to taste me.  I hope the vapors that emit
  from his dark hole is not offensive!
Now, I know I just didn't fall just to get trampled on!
Oh, please, scoop me up with some of my brethren to form a figure
  this will make our existence last a little longer!
