You measure my life in hours
I serve you by expiring
I vanish faster when I am thin
and slower when I am thick
The wind is my energy
What am I?

I make a loud sound when I’m changing. When I do change, I get bigger but weigh less. What am I?

It's pretty hard to give up.
If you remove a part of it, you will be left with a bit.
Even if you remove another part, the bit still remains.
Remove one more and it still remains.

What is it?

I’m tall when I’m young, and I’m short when I’m old. What am I?

I am not a bull but I have horns.
I am not an ass but I have a pack saddle.
Wherever I go, I leave silver behind me.

Who am I?

There was a greenhouse.
Inside the greenhouse, there is a white house.
Inside the white house, there is a red house.
Inside the red house, there are lots of babies.

What is It?

What is in seasons, seconds, centuries and minutes but not in decades, years or days?

What am I?

Take one out and scratch my head, I am now black but once was red. What am I?

If your uncle’s sister is not your aunt, what relation is she to you?
