WHAT AM I RIDDLES

Bright as diamonds, Loud as thunder, Never still, A thing of wonder. What am I?

When you stop and look, you can always see me. If you try to touch you cannot feel me. I cannot move, but as you near me, I will move away from you. What am I?

Crimson I am born, yellow I dance, ebony I die. What am I?

Large as a mountain, small as a pea, Endlessly swimming in a waterless sea. What am I?

Dark with white markings, And smooth like a rock. Where learning occurs, I help convey thought. What am I?

I'm blue at day and black at night; I do contain some creatures born and died. What am I?

I'm by nature solitary, scarred by spear and wounded by sword, weary of battle. I frequently see the face of war, and fight hateful enemies; yet I hold no hope of help being brought to me in the battle, before I'm eventually done to death. In the stronghold of the city sharp-edged swords, skilfully forged in the flame by smiths, bite deeply into me. I can but await a more fearsome encounter; it is not for me to discover in the city any of those doctors who heal grievous wounds with roots and herbs. The scars from sword wounds gape wider and wider; death blows are dealt to me by day and by night.

What am I?

I can be all colours of the rainbow, Or have no colour at all. Sometimes I'm empty, Sometimes I'm full. What am I?

I know a word of letters three. Add two, and fewer there will be! What Word Am I?

I am a food,

I have only three letters in my name;

Leave the first,

I still sound the same.

What am I?
