FOUR RHYMING RIDDLES

1)

I'm tall in the morning,

Short at noon;

Gone at night,

I'll be back soon.

2)

Three little letters,

A paradox to some;

The worse that it is,

The better it becomes.

An iron horse with a flaxen tail,

The faster the horse runs,

The shorter the tail becomes.

4)

Found in a shell, but not the sea,

Both yellow and white it can be.
