Answer:
I am all around you but you cannot see me. I have no throat but you can hear me. Valued during summer but despised in the winter.
I save lives on the ground and in the air
Sometimes dark and sometimes bright I make my way among twinkling lights. Seas and oceans obey my call yet mountains I cannot move at all. My face is marred and gray But I'm majestic anyway
I turn around once. What is out will not get in. I turn around again. What is in will not get out.
Lovely and round, I shine with pale light, Grown in the darkness, a ladyβs delight.
Though not a plant, has leaves. Though not a beast, has spine. Though many wouldn't need this thing, It's more valuable than wine.
