Answer:
I have a head tail but no arms and legs.
I lose my head in the morning and regain back it at night.
Every night I'm told what to do, and each morning I do what I'm told. But I still don't escape your scold. What am I?
I shift around though always slowly. I never move more than a few inches at a time. A large movement by me can kill many people. I am huge yet unseen by humans.
I am the thing that is used to make your weight. What am I?
It flows out of the soil, It burns you if it boils, And holds us in its coils, More valuable than gold, As black as it is old.
