Tell me something, Which breaks but never falls down?

It is as large as a mountain, as small as a pea, endlessly swimming in a waterless ocean.

What is it?

Try to search him in the mountain
And you can find him in the creek
He has no mouth -
Yet he speaks in every tongue
He has no ears -
And yet will answer every cry
Always having the final word.

Who is HE?

There is a thief, who steals from the rich,
And gives unto the poor.
She pays out in argent,
That which she stole in or.
Of she and he she robs,
More beauteous she by far:
She I love to gaze on;
Him I’ll never dare.

A whole dale filled out, but nod even a single full hand.. what is it?
