Answer:
As a state in the USA, I am round on both sides and high in the middle. What am I?
With a halo of water and a tongue of wood; stone as skin long I stood.
I am your most powerful weapon; I come before your eyes. I help you seek the truth, yet I often give you lies. What am I?
I am gentle enough to soothe your skin light enough to fly in the sky and strong enough to crack rocks.
I look at you you look at me I raise my right you raise your left.
Strip the skin under my skin, and my flesh you'll reveal. It tastes sweet and tart, now throw out the peel. What is it?
