Answer:
Lovely and round I shine with pale light grown in the darkness a lady's delight.
I save lives on the ground and in the air
I need to be taken before you can have me. What am I?
Deposit red liquid in me.
What goes through cities and fields but never moves?
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.
