Preliminary: Rocks and Minerals

[sciencegeek100]

When gneiss (the rock, not the SciOlyer) experiences heat & pressure, what does it metamorphose into? Assuming it metamorphoses into anything.

It's the final stage of foliated metamorphic rock. So it gets metamorphosed...into more gneiss.

Though if you gneiss from the surface and then start applying heat and pressure, I'm pretty sure it'll go through the cycle again just like any other rock, starting with slate. I'm not 100% sure about that though (I haven't taken Petrology yet)

it will just become wavier but it will still be nice gneiss

Preliminary discussion for Rocks&Minerals.

I've been looking through old tests now, and it looks like the event is all about the Identification part. If you can ID it, you will do great, since almost every question is easily located online, and the few things besides IDing (Bowen reaction series, aging rocks, Mohs scale, rock cycle, etc.) aren't too difficult.

I thought I heard from somewhere there is now a new scale is use that replaced the moh's scale for measuring hardness, anybody know if this is true and if so, what its called

I've never heard that.

Will there be a list of rock and mineral types that we could be possibly asked about or asked to identify? (Like how there was the list of species for ornithology.)

Yeah, take a look at the trial rules. I can guarantee that our list will be at least 95% similar to it.

R&M wasn't a trial event this year in NY, but I think this is an ID event with the list and field guides, etc.

It is exactly that
R&M is a lot like fossils, there is going to be A LOT Of ID, but its also going to involve general info.

Would using the old list be helpful?

Yes - The new list will probably be about ~90% the same.

I found the trial event rules here: http://bohr.eri.harvard.edu/bobg/RocksAndMinerals.pdf
This looks like a good event to do next year. I studied Rocks and Minerals in 4th grade.

[Cheesy Pie]

Studied them this year.
