1)What is it that when you take away the whole,
you still have some left over?

2)Forward I am heavy, backward I am not. What am I?

3)Though I have no color,
I am sometimes white.
And you can't avoid me,
Though try as you might.
I'm useful for hiding things no one can see
And rarely, if ever, does good come from me.

4)Take off my skin
I won't cry, but you will! What am I?

5)Where do you find roads without vehicles, forests without
trees, and cities without houses?
