Random Riddles...

Here are some riddles that I found in a Drangonology book that my friend let me borrow. They are kinda hard...in a way...
1.) Weight in my belly,
Trees on my back,
Nails in my ribs,
Feet I do lack.

2.) The wave, over a wave, a weird thing I saw,
Through-wrought, and wonderful ornate:
A wonder on the waves, water becomes bone.

3.) What gets wetter the more it dries?

4.) The part of the bird
that is not inthe sky,
which can swim in the ocean
and always stay dry.
What is it?

5.) Can you tell what rhyms with moon,
And could be written on a page,
Or on a rock for age on age,
This ancient letter tell me soon!

6.) Like a coat of shining mail,
On my back down to my tail,
On a snake from tail to throat,
Never on a cow or goat,
Sounds like eight notes on a harp,
And you'll find them on a carp.

I have more, but I don't wanna put 'em up yet...See if you can answer them.:D
