A father's child, a mother's child, yet no one's son.

Who am I?

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

As a whole I am both
safe and secure.

Behead me and I become
a place of meeting.

Behead me again and I am
the partner of ready.

Restore me, and I become
the domain of beasts.

What am I?

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?

What is full of holes but still holds water?

Pronounced as 1 letter, And written with 3, 2 letters there are, and 2 only in me. I’m double, I’m single, I’m black blue and grey, I’m read from both ends, and the same either way. What am I?

You see me once in June, twice in November, and not at all in May. What am I?

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

Two in a corner, one in a room, zero in a house, but one in a shelter. What am I?

I have cities, but no houses. I have mountains, but no trees. I have water, but no fish. What am I?
