Rocks & Minerals B/C

[quizbowl]

Hi I'm new here, and I competed in my state meet last year, and there were questions about shapes of the minerals (like conical, etc) that really threw my teammate and I. Does anyone have any suggestions as to where I can find resources for this type of question?
Thanks!
*ps I know what the words mean, I was just wondering if there was a uniform list or a resource where I can find it*

...I don't remember this station. Care to clarify? [I took this last year and got 2nd.]

Are they referring to habit by any chance?

There was nothing in relation to "conical". Yes, there was a station involving mineral habit.

To add an image use the following: [ img] Insert image URL here [/img]
Just a note, to get it to work, you have to take out the space before the first 'img' bracket.

To hide something use the following: [ hide]Title - What you want people to see|What you want to hide, like, say an image.[/hide]
Once more, take out the space before the first 'hide' bracket, otherwise it won't work.

So if you wanted to hide that image, here's what you would use:

What does it mean when they put Goethite/ Limonite.. They're very similar but they are still two different minerals...

I think it's because goethite is anhydrous, whereas limonite is a hydrate of goethite. Basically, the only difference is that limonite has some H2O and goethite doesn't. Another, more colorful example would be cobalt (II) chloride. The red/pink/purple color is the hydrate, and the blue is anhydrous. It's still the same compound with the exception of the presence of water. I hope this helps a little bit.

just to make conversation, does anyone have any interesting facts they would like to share? To help prepare for that one weird question on the test that seems random and irrelevant.

Geographic features appeared on the Rocks test yesterday at Boyceville. Hadn't studied that yet with my partner so we had no clue what to put down. Even if I have nothing on it yet I'd think other people would find this beneficial to study.

Also, would anyone have a link to information about the rock side of the Bowen's reaction series? I can't seem to find it.

(Edit: Sorry, wrong word choice.)
