WHAT AM I RIDDLES

I sound a color,

But that's the old me;

I grow near the water;

I'm what your doing.

What am I?

Pregnant every time you see her, yet she never will give birth. What is she?

I exist, but have no material form. I am made of numbers, but appear square. I build upon other of my own, but do not topple down. I sit still and do nothing, but I'm still useful. What am I?

My full powers come when my makers are dead; I await a heavy hat to put on my head. What am I?

What is the noblest musical instrument?

I cover what's real, hide what is true, but sometimes bring out the courage in you. What am I?

I am not found on any ground,
But always in the air;
Though charged each cloud with thunder loud,
You can not find me there.
Now, if from France you choose to dance
Your way just into Spain,
I there am seen, and near the queen,
In hail, in mist, and rain.

What am I?

If a man carried my burden he would break his back. I am not big but leave silver in my tracks. What am I?

My name starts with "rain" and ends with the first letter of my name. I get mistaken for other things a lot. I am usually present in children's stories. I am usually flying in mid-air too. What am I?

I can kill people, but without me there would be no people. I was born long ago and will someday die. I can cause fire and am a magician with water. I have more brothers than any person. There is very little that can stop me.

What am I?
