I speak without a mouth and hear without ears. I have no body, but I come alive with the wind. What am I?
An echo.
You measure my life in hours, and I serve you by expiring. I'm quick when I'm thin and slow when I'm fat. The wind is my enemy. What am I?
A candle.
Voiceless it cries,
Wingless flutters,
Toothless bites,
Mouthless mutters.
Wind.
This thing all things devours;
Birds, beasts, trees, flowers;
Gnaws iron, bites steel;
Grinds hard stones to meal;
Slays king, ruins town,
And beats mountain down.
Time.
What has roots as nobody sees,
Is taller than trees,
Up, up it goes,
And yet never grows?
Mountains.
I have keys but open no locks. I have space but no room. You can enter, but you can't go inside. What am I?
A keyboard.
The more of this there is, the less you see. What is it?
Darkness.
What comes once in a minute, twice in a moment, but never in a thousand years?
The letter "M".
What has to be broken before you can use it?
An egg.
Alive without breath,
As cold as death;
Never thirsty, ever drinking,
All in mail never clinking.
Fish.
Thirty white horses on a red hill,
First they champ,
Then they stamp,
Then they stand still.
Teeth.
A box without hinges, key, or lid,
Yet golden treasure inside is hid.
Eggs.
What is so fragile that saying its name breaks it?
Silence.
I am not alive, but I grow; I don't have lungs, but I need air; I don't have a mouth, and I can drown. What am I?
Fire.
What can travel around the world while staying in a corner?
A stamp.
