and a rock?

Dictionary
Stone
noun
1 the hard, solid, nonmetallic mineral matter of which rock is made

I really am looking for a geological answer to this. I am understanding that a stone is the mineral that makes up a rock. Yet a thesaurus gives a synonym for stone the word "rock." So are they the same. Or is it because one makes up the other.

I've got my own reasons for why this is important to me, but it is, so I was looking for a scientific clarification.

Answers appreciated. Links are fine.

Thank you.

So many tons of beets are left in the fields each year. It's such a waste! If they (Brazil) can make ethanol out of sugar cane , why can't we use sugar beets? Is our technology so far behind them?

All I have to say is that is what you get when you put wild animals in a cage and think they will act civil. And what is with people shooting endangered animals to death dont they have tranquilizers at the zoo that they have ready. SERIOUSLY!!

My friend told me that in the 1950's Colorado was so cold in the winter, and global warming helped them. She said that people have been saying that this might happen soon, and that the hottest weather will be 70 degrees. Is that true or false? Care to explain!

Do 4 fins offer more stability or 3 fins? I'm using cardboard or some type of light weight board to construct the fins. Based on y opinion, I believe that 4 fins will offer more stability due to more surface area, but I would like to hear other opinions. I am building a water rocket btw

Use Descartes' Rule of Signs to analyze the zeros of the following. List all possibilities.

P(x) = x^5 - 4x^4 + 3x^3 + 2x - 6

P(x) = -5x^4 + x^3 + 2x^2 - 1

P(x) = 2x^5 + 7x^3 + 6x^2 - 2

Could someone explain how I would do this? Maybe show an example? Thank You! :)
