I stand in silence yet speak in rings, I drink from the earth but never from springs. In spring I wake, in autumn I fall, I shelter the weak and outlive us all. My arms reach wide but never embrace, I mark the years on my weathered face. Cut me down and I still remain. In books, in homes, in ships at sea and trains. What am I?

I stand tall but have no legs, hold a flower, but have no hands. I'm a plant's support, its central core, what am I, say no more?

In the cradle of salt and sand, a whispering spiral tells tales of distant waves. A souvenir from Poseidon's realm, capturing the ocean's lullaby.

From a cow or mamma’s breast, This white substance is the best

The only thing I can do with this riddle is weep. What am I?
