I have some great riddles that had all my collegues stressing to work out.
I come out of the earth,
I am sold in the market.
He who buys me cuts off my tail,
Takes off my suit of silk,
And weeps beside me when I am dead...WHAT AM I?

"I'm as small as an ant, as big as a whale. I'll approach like a breeze, but can come like a gale. By some I get hit, but all have shown fear. I'll dance to the music, though I can't hear. Of names I have many, of names I have one. I'm as slow as a snail, but from me you can't run. What am I?"

"I dig out tiny caves, and store gold and silver in them. I also build bridges of silver and make crowns of gold. They are the smallest you could imagine. Sooner or later everybody needs my help, yet many people are afraid to let me help them."
"I have a hundred legs, but cannot stand. I have a long neck, but no head. I cannot see, but I'm neat and tidy as can be. What am I?"
"I know what my job is, The point has been made. You say I have a big head, And you're right, I'm afraid. So put me in my place, And then leave me alone. What I need most, Is someone to drive me home."
"My life can be measured in hours, I serve by being devoured. Thin, I am quick. Fat, I am slow. Wind is my foe. What am I?"
"If a man tried to carry my burden, He would surely break his back. I am not rich, But, where're I go, I leave silver in my track. What am I?"
I have streets but no pavement. I have cities but no buildings. I have forests yet no trees. I have rivers yet no water. What am I?

"You walk into the forest and get me, You sit down to look for me but can't find me, You get up and leave with me. What am I?"
My top and bottom are twins of a kind.
The middle of me makes one body combined.
I'm used to pass time and provide quite a thrill.
If I stand tall and still, run faster I will.
I have keys that open no locks, I have space, but there is no room. You can enter, but you can’t go in. I am?

It has no top or bottom but it can hold flesh, bones and blood all at the same time. What is this object?

I'll await all answers, and after a week I will post the correct ones if no one has managed to solve the riddles by then!
